Subject: * sysdeps/mips/dl-machine.h (ELF_MACHINE_NO_RELA): Delete.
(elf_machine_reloc): New function, retaining the body of
elf_machine_rel. Take the reloc's r_info field as an argument,
not the reloc itself. Add extra r_addend and inplace_p arguments.
When inplace_p is false, use r_addend as the addend, not the contents
of the relocation field. Hoist the conversion of reloc_addr to
"ELFW(Addr) *". Don't try to apply TLS relocations against
undefined symbols. Add R_MIPS_GLOB_DAT support.
(elf_machine_rel, elf_machine_rela): Use elf_machine_reloc.
(elf_machine_lazy_rel): Change the reloc type from ElfW(Rel)
to ElfW(Rela).
