That really is up to one of the MIPS maintainers. As I said in
http://sourceware.org/ml/binutils/2013-02/msg00159.html the MIPS backend
wants _GLOBAL_OFFSET_TABLE_ dynamic for some reason.
bh = NULL;
if (! (_bfd_generic_link_add_one_symbol
(info, abfd, "_GLOBAL_OFFSET_TABLE_", BSF_GLOBAL, s,
0, NULL, FALSE, get_elf_backend_data (abfd)->collect, &bh)))
return FALSE;
h = (struct elf_link_hash_entry *) bh;
h->non_elf = 0;
h->def_regular = 1;
h->type = STT_OBJECT;
elf_hash_table (info)->hgot = h;
if (info->shared
&& ! bfd_elf_link_record_dynamic_symbol (info, h))
return FALSE;
I think that is just plain wrong, but I don't know the history of this
code.
Another issue is that your simple one-line patch potentially requires
testsuite changes. Have you run the ld testsuite on a native MIPS
target after making your change? How about the glibc testsuite?
