PR gold/12980
* i386.cc (Target_i386::Scan::global): For a GOT reloc, use a
GLOB_DAT relocation rather than a RELATIVE relocation for a
protected symbol when creating a shared library.
* x86_64.cc (Target_x86_64::Scan::global): Likewise.
* testsuite/protected_1.cc (f2, get_f2_addr): New functions.
* testsuite/protected_main_1.cc (main): Test that protected
function has same address.
