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.
