H.J. Lu 3d9499950a Check GOTOFF reloc against protected data on x86 
R_386_GOTOFF/R_X86_64_GOTOFF64 relocation shouldn't be used against
protected data symbol on x86 since with copy relocation, address of
protected data defined in the shared library may be external.

This patch will break building shared libraries with protected data
symbols using GCCs older than GCC 5 without the bug fix for

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

GCC backport request should be made in the GCC bug report above.

	PR ld/pr17709

	* elf64-x86-64.c (elf_x86_64_relocate_section): Also check
	R_X86_64_GOTOFF64 against protected data symbol when building
	shared library.
