Fix LuaJIT build script to add dependency files for luajit executable.

The luajit executable should now be able to generate Lua bytecode files in Bin/ directory under the project root directory or in any directory when Urho3D SDK is installed in the filesystem.

+-- Sending small code snippets to an external disassembler and mixing the

+--
+-- The output format is very similar to what ndisasm generates. But it has

+-- 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.

+--
+-- 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"

+----------------------------------------------------------------------------
+--
+-- 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.
+--
