Fixed LuaJIT build on Linux, both native and cross-compiling.

The following platforms should be now supported:
Windows, Linux, Mac OS X, IOS, Android, and Raspberry Pi. Not all platforms are fully tested yet.

Cross-compilation may work on GCC/CLang only.

---
--- Copyright (C) 2005-2013 Mike Pall. All rights reserved.
--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
---
--- This module lists the bytecode of a Lua function. If it's loaded by -jbc
--- it hooks into the parser and lists all functions of a chunk as they
--- are parsed.
---
--- Example usage:
---
---   luajit -jbc -e 'local x=0; for i=1,1e6 do x=x+i end; print(x)'
---   luajit -jbc=- foo.lua
---   luajit -jbc=foo.list foo.lua
---
--- Default output is to stderr. To redirect the output to a file, pass a
--- filename as an argument (use '-' for stdout) or set the environment
--- variable LUAJIT_LISTFILE. The file is overwritten every time the module
--- is started.
---
--- This module can also be used programmatically:
---
---   local bc = require("jit.bc")
---
---   local function foo() print("hello") end
---
---   bc.dump(foo)           --> -- BYTECODE -- [...]
---   print(bc.line(foo, 2)) --> 0002    KSTR     1   1      ; "hello"

---     write = function(t, ...) io.write(...) end,

---
--- Copyright (C) 2005-2013 Mike Pall. All rights reserved.
--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
--- This is a helper module used by the LuaJIT machine code dumper module.
---
--- Sending small code snippets to an external disassembler and mixing the
--- output with our own stuff was too fragile. So I had to bite the bullet
--- and write yet another x86 disassembler. Oh well ...
---
--- The output format is very similar to what ndisasm generates. But it has
--- been developed independently by looking at the opcode tables from the
--- Intel and AMD manuals. The supported instruction set is quite extensive
--- and reflects what a current generation Intel or AMD CPU implements in
--- 32 bit and 64 bit mode. Yes, this includes MMX, SSE, SSE2, SSE3, SSSE3,
--- SSE4.1, SSE4.2, SSE4a and even privileged and hypervisor (VMX/SVM)
--- instructions.
---
--- Notes:
--- * The (useless) a16 prefix, 3DNow and pre-586 opcodes are unsupported.
--- * No attempt at optimization has been made -- it's fast enough for my needs.
--- * The public API may change when more architectures are added.

--- LuaJIT compiler dump module.
---
--- Copyright (C) 2005-2013 Mike Pall. All rights reserved.
--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
---
--- This module can be used to debug the JIT compiler itself. It dumps the
--- code representations and structures used in various compiler stages.
---
--- Example usage:
---
---   luajit -jdump -e "local x=0; for i=1,1e6 do x=x+i end; print(x)"
---   luajit -jdump=im -e "for i=1,1000 do for j=1,1000 do end end" | less -R
---   luajit -jdump=is myapp.lua | less -R
---   luajit -jdump=-b myapp.lua
---   luajit -jdump=+aH,myapp.html myapp.lua
---   luajit -jdump=ixT,myapp.dump myapp.lua
---
--- The first argument specifies the dump mode. The second argument gives
--- the output file name. Default output is to stdout, unless the environment
--- variable LUAJIT_DUMPFILE is set. The file is overwritten every time the
--- module is started.
---
--- Different features can be turned on or off with the dump mode. If the
--- mode starts with a '+', the following features are added to the default
--- set of features; a '-' removes them. Otherwise the features are replaced.
---
--- The following dump features are available (* marks the default):
---
---  * t  Print a line for each started, ended or aborted trace (see also -jv).
---  * b  Dump the traced bytecode.
---  * i  Dump the IR (intermediate representation).
---    r  Augment the IR with register/stack slots.
---    s  Dump the snapshot map.
---  * m  Dump the generated machine code.
---    x  Print each taken trace exit.
---    X  Print each taken trace exit and the contents of all registers.
---
--- The output format can be set with the following characters:
---
---    T  Plain text output.
---    A  ANSI-colored text output
---    H  Colorized HTML + CSS output.
---
--- The default output format is plain text. It's set to ANSI-colored text
--- if the COLORTERM variable is set. Note: this is independent of any output
--- redirection, which is actually considered a feature.
---
--- You probably want to use less -R to enjoy viewing ANSI-colored text from
--- a pipe or a file. Add this to your ~/.bashrc: export LESS="-R"

--- Verbose mode of the LuaJIT compiler.
---
--- Copyright (C) 2005-2013 Mike Pall. All rights reserved.
--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
---
--- This module shows verbose information about the progress of the
--- JIT compiler. It prints one line for each generated trace. This module
--- is useful to see which code has been compiled or where the compiler
--- punts and falls back to the interpreter.
---
--- Example usage:
---
---   luajit -jv -e "for i=1,1000 do for j=1,1000 do end end"
---   luajit -jv=myapp.out myapp.lua
---
--- Default output is to stderr. To redirect the output to a file, pass a
--- filename as an argument (use '-' for stdout) or set the environment
--- variable LUAJIT_VERBOSEFILE. The file is overwritten every time the
--- module is started.
---
--- The output from the first example should look like this:
---
--- [TRACE   1 (command line):1 loop]
--- [TRACE   2 (1/3) (command line):1 -> 1]
---
--- The first number in each line is the internal trace number. Next are
--- the file name ('(command line)') and the line number (':1') where the
--- trace has started. Side traces also show the parent trace number and
--- the exit number where they are attached to in parentheses ('(1/3)').
--- An arrow at the end shows where the trace links to ('-> 1'), unless
--- it loops to itself.
---
--- In this case the inner loop gets hot and is traced first, generating
--- a root trace. Then the last exit from the 1st trace gets hot, too,
--- and triggers generation of the 2nd trace. The side trace follows the
--- path along the outer loop and *around* the inner loop, back to its
--- start, and then links to the 1st trace. Yes, this may seem unusual,
--- if you know how traditional compilers work. Trace compilers are full
--- of surprises like this -- have fun! :-)
---
--- Aborted traces are shown like this:
---
--- [TRACE --- foo.lua:44 -- leaving loop in root trace at foo:lua:50]
---
--- Don't worry -- trace aborts are quite common, even in programs which
--- can be fully compiled. The compiler may retry several times until it
--- finds a suitable trace.
---
--- Of course this doesn't work with features that are not-yet-implemented
--- (NYI error messages). The VM simply falls back to the interpreter. This
--- may not matter at all if the particular trace is not very high up in
--- the CPU usage profile. Oh, and the interpreter is quite fast, too.
---
--- Also check out the -jdump module, which prints all the gory details.
