This patch adds IFUNC support for arm gold backend.
This is a feature required in chromeos arm development work.
Tested:
1) Built passed all-gold on x86_64 machine
2) Tested with basic gold aarch64 ifunc unittests -
a) global ifunc, statically/non-statically linked
b) local ifunc, statically/non-statically linked
c) global/local, other shared library routine mixed,
statically/non-statically linked
d) arm/thumb mode ifunc
e) linking chrome browser passed
