[gold] PATCH: PR gold/18628: gold IFUNC testsuite failures with GCC 5

[H.J. Lu]

GCC 5 will generate a relocation for protected symbol:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248

when compiling for a shared library.  It is undefined to access protected
symbol in IFUNC selector function inside a shared library.

OK for master?

H.J.
