- Removed generic implementation of TObjData.sectionname, its existence is useless because it is completely overridden by all TObjData descendants.

* ELF linker: moved some code (which must be executed only once when linking with separate debug file) from MemPos_Start into AfterUnusedSectionRemoval, this removes some checks and simplifies things.

+ ELF linker. Works on x86_64-linux and i386-linux good enough to pass the testsuite, but still requires a lot of work in nearly all aspects. In particular, no attempt to resolve symbols from shared libs is done, everything is just treated as imports. Symbol versioning isn't supported either.

* When writing section names of .o files, let sh_name of sections with relocations point into names of corresponding relocation sections past the .rel/.rela prefix. In case of smartlinked sections this saves almost half of .shstrtab section size.

- Do not create any default object sections. On targets with section-based smartlink these sections remain empty and only cause linker to do useless job of removing them. The same happens when loading object files because duplicate section names are allowed at that time. On targets without smartlink they don't stay empty, but the internal assembler creates sections when required, so not creating initial sections effectively doesn't change anything.

* If relocation to a local label cannot be translated into (section+offset), then the target symbol must be written into symbol table. Fixes IE 200603012 in number of tests with -Cg on i386-linux (and possibly other targets with internal ELF assembler).

* Fixed alignment of '.data' section, which got accidentally changed from 16 to 8 by r21374, causing e.g. tests/test/tasm3.pp to crash if compiled without -Cg and on target without tf_smartlink_sections. The root problem is not here, however: if appending data with higher alignment to a section with lower alignment, we likely need to raise the alignment of section.
