Fix broken -Bsymbolic-functions

For selected targets.  The testcase reveals a number of targets that
still need fixing.

bfd/
	* elf32-arm.c (elf32_arm_final_link_relocate): Use SYMBOLIC_BIND to
	check if a symbol should be bound symbolically.
	* elf32-hppa.c (elf32_hppa_check_relocs,
	elf32_hppa_adjust_dynamic_symbol, elf32_hppa_relocate_section,
	elf32_hppa_finish_dynamic_symbol): Likewise.
	* elf32-m68k.c (elf_m68k_check_relocs,
	elf_m68k_relocate_section): Likewise.
	* elf32-nios2.c (nios2_elf32_relocate_section,
	nios2_elf32_check_relocs, allocate_dynrelocs): Likewise.
	* elf32-tic6x.c (elf32_tic6x_finish_dynamic_symbol,
	elf32_tic6x_relocate_section): Likewise.
ld/testsuite/
	* ld-elf/symbolic-func.s,
	* ld-elf/symbolic-func.r: New test.
	* ld-elf/elf.exp: Run it.
