Don't segfault in mips reloc special_functions
A symbol defined in a section from a shared library will have a NULL
section->output_section during linking.
* elf32-mips.c (gprel32_with_gp): Don't segfault on NULL
symbol->section->output_section.
* elf64-mips.c (mips_elf64_gprel32_reloc): Likewise.
* elfn32-mips.c (mips_elf_gprel16_reloc): Likewise.
(mips_elf_literal_reloc, mips_elf_gprel32_reloc): Likewise.
(gprel32_with_gp, mips16_gprel_reloc): Likewise.
* elfxx-mips.c (_bfd_mips_elf_gprel16_with_gp): Likewise.
(_bfd_mips_elf_generic_reloc): Likewise.
