I'm just confirming that the ld error is fixed with binutils-2.17: it's the exact same error as gcc-4.6 and I did have a built gcc-4.6/binutils-2.17 combo on loongson. No reason to suspect that gcc-4.8 won't build with binutils-2.17 as well. I don't have the time to test gcc-4.8/binutils-2.17 right now but I will if people really want.

mips64[el] for gcc 4.8 (unfinished)
I've invested some time into adding the mips64(el) backend. It gets
quite far (xgcc seems to be fine), but then our ld takes a dump:
/usr/bin/ld: not enough GOT space for local GOT entries
/usr/bin/ld: BFD 2.15 internal error, aborting at /usr/src/gnu/usr.bin/binutils
/bfd/elfxx-mips.c line 6483 in _bfd_mips_elf_relocate_section
/usr/bin/ld: Please report this bug.
Log: http://www.tmux.org/~tobiasu/tmp/gcc48-mips64-build.txt
Others have run into this, and it's possibly fixed in newer binutils,
but I have not been able to make sense of the BFD guts enough to fix ld.
Question is, should I commit this in its current form so others can try
their luck? I'm pretty sure this patch is 95% there.
Untested on mips64el, but I don't expect wonders...
