George Rimar ffb673515e [ELF] - R_386_GOT32 relocation calculation fix. 
R_386_GOT32 has multiple descriptions:

"System V Application Binary Interface Intel386 Architecture Processor Supplement Version 1.1" (https://github.com/hjl-tools/x86-psABI/wiki/intel386-psABI-1.1.pdf), p36 contains next calculation for R_386_GOT32: G + A - GOT.
SYSTEM V APPLICATION BINARY INTERFACE 4 (https://refspecs.linuxfoundation.org/elf/abi386-4.pdf, p78) tolds us its G + A - P.
Oracle docs (https://docs.oracle.com/cd/E19455-01/816-0559/chapter6-26/index.html) says its should be G + A.

gold/bfd calculates it as "G + A - GOT", but GOT means the end of the GOT section.
Patch fixes current calculation to gold/ld behavior.

README.md

The New ELF Linker

This directory contains a port of the new PE/COFF linker for ELF.

Overall Design

See COFF/README.md for details on the design. Note that unlike COFF, we do not distinguish chunks from input sections; they are merged together.

Capabilities

This linker can link LLVM and Clang on Linux/x86-64 or FreeBSD/x86-64 "Hello world" can be linked on Linux/PPC64 and on Linux/AArch64 or FreeBSD/AArch64.

Performance

Achieving good performance is one of our goals. It's too early to reach a conclusion, but we are optimistic about that as it currently seems to be faster than GNU gold. It will be interesting to compare when we are close to feature parity.
