Gold: Don't fail on R_X86_64_[REX_]GOTPCRELX relocations
This patch updates gold to treat the R_X86_64_GOTPCRELX and
R_X86_64_REX_GOTPCRELX relocations proposed in
https://groups.google.com/forum/#!topic/x86-64-abi/n9AWHogmVY0
the same as R_X86_64_GOTPCREL. FIXME: Gold should perform the
transformations as suggested.
elfcpp/
* x86_64.h (R_X86_64_GOTPCRELX): New.
(R_X86_64_REX_GOTPCRELX): Likewise.
gold/
* x86_64.cc (Target_x86_64<size>::Scan::get_reference_flags):
Treat R_X86_64_GOTPCRELX and R_X86_64_REX_GOTPCRELX the same
as R_X86_64_GOTPCREL.
(Target_x86_64<size>::Scan::local): Likewise.
