Gold: Don't fail on R_386_GOT32X relocation
This patch updates gold to treat the R_386_GOT32X relocation proposed in
https://groups.google.com/forum/#!topic/ia32-abi/GbJJskkid4I
the same as R_386_GOT32. FIXME: Gold should perform the transformations
as suggested.
elfcpp/
* i386.h (R_386_GOT32X): New.
gold/
* i386.cc (Target_i386::Scan::get_reference_flags(): Treat
R_386_GOT32X the same as R_386_GOT32.
(Target_i386::Scan::local): Likewise.
(Target_i386::Scan::possible_function_pointer_reloc): Likewise.
(Target_i386::Scan::global): Likewise.
(Target_i386::Relocate::relocate): Likewise.
(Target_i386::Relocatable_size_for_reloc::get_size_for_reloc):
Likewise.
