Replace SYMBOLIC_BIND with SYMBOL_REFERENCES_LOCAL

When checking R_386_GOTOFF/R_X86_64_GOTOFF64 for building shared library,
we should check SYMBOL_REFERENCES_LOCAL instead of SYMBOLIC_BIND to cover
more cases.

bfd/

	* elf32-i386.c (elf_i386_relocate_section): Replace SYMBOLIC_BIND
	with SYMBOL_REFERENCES_LOCAL when checking R_386_GOTOFF against
	protected data symbol when building shared library.
	* elf64-x86-64.c (elf_x86_64_relocate_section): Check
	R_X86_64_GOTOFF64 against undefined symbol and replace
	SYMBOLIC_BIND with SYMBOL_REFERENCES_LOCAL when checking
	R_X86_64_GOTOFF64 against protected data symbol when building
	shared library.

ld/testsuite/

	* ld-i386/i386.exp: Run protected6a.
	* ld-i386/protected6.d: Renamed to ...
	* ld-i386/protected6a.d: This.
	* ld-x86-64/hidden4.d: New file.
	* ld-x86-64/hidden4.s: Likewise.
	* ld-x86-64/hidden5.d: Likewise.
	* ld-x86-64/hidden5.s: Likewise.
	* ld-x86-64/protected6.d: Renamed to ...
	* ld-x86-64/protected6a.d: This.
	* ld-x86-64/x86-64.exp: Run hidden4, hidden5, protected6a,
	protected7a and protected7b.
