Mark global with hidden attribute
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.
PR gold/18628
* testsuite/ifuncdep2.c (global): Change protected to hidden.
* testsuite/ifuncmod1.c (global): Likewise.
* testsuite/ifuncmod5.c (global): Likewise.
