* elfxx-mips.c (sort_dynamic_relocs): Sort relocations against the
same symbol by increasing r_offset.
(sort_dynamic_relocs_64): Likewise. Fix comparisons between very
large and very small symbol indexes.
ld/testsuite/
* ld-mips-elf/tlslib-o32-hidden.got: Sort relocations against the
same symbol in order of increasing r_offset.
* ld-mips-elf/tls-multi-got-1.got: Likewise.
* ld-mips-elf/tls-hidden3.r: Likewise.
* ld-mips-elf/tls-hidden4.r: Likewise.
(mips_elf_local_got_index): Use the hash table entry to record
the GOT index of forced-local symbols.
(mips_elf_initialize_tls_index): Rearrange code. Store the index
in either the hash table entry or the mips_got_entry, not both.
Add more commentary.
(mips_elf_multi_got): Make sure the g->next is nonnull when calling
mips_elf_initialize_tls_index.
