0aa7204707 + Added codes of dynamic relocations to TElfTarget; since most targets use similar dynamic relocation model differing only in code values, this will allow to do majority of handling in the base class.

c4d8396158 * Function RelocName made a member of TElfTarget, so it can be used outside of TElfExeOutput class. 
* Methods ReportNonDSOReloc and ReportRelocOverflow moved to TElfExeOutput, they are applicable to all target-specific descendants.

d79761c607 * Changed TElfTarget from class to record, so it can contain data members while remaining statically allocated. 
* Moved target-dependent constants into ElfTarget records, eliminates a lot of $ifdef's in ogelf.pas.
+ Added TElfTarget.loadsection hook and pass unknown sections to it.

6d70009f06 + 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. 
x86_64 is the most elaborated, has some degree of indirect function (GNU_IFUNC) and TLS support, so it is even able to link with static libc/pthreads code (tw14265) and produce an executable that can launch (but still fails due to invalid DWARF unwind info).

i386 produces working shared libraries if they are compiled with -Cg, without one your mileage may vary. tw14265 does not link yet due to missing COMDAT group support.
