They were both pointing to the start of the got, not the end.

[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.

[ELF] - Lazy relocations support for x86 target.
...
Patch implements lazy relocations for x86.
One of features of x86 is that executable files and shared object files have separate procedure linkage tables. So patch implements both cases.
Detailed information about instructions used can be found in http://docs.oracle.com/cd/E19620-01/805-3050/chapter6-1235/index.html (search: x86: Procedure Linkage Table).
