Applied patch to fix mips elf64 assertion failures

[Richard Sandiford]

Using elf64-mips.c, information gathered from relocs against indirect
symbols wasn't being copied to the real symbol's hash table.  Test cases like:

        .dword  abort

would then cause an assertion failure for mips64-linux-gnu.

The reason was that elf64-mips.c (unlike elf32-mips.c and elfn32-mips.c)
wasn't using _bfd_mips_elf_copy_indirect_symbol.

Tested on mips64-linux-gnu, installed as obvious.

	* elf64-mips.c (elf_backend_copy_indirect_symbol): Define.
