FWIW, there=E2=80=99s a discussion of MIPS ABIs at
<http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64> and related
pages.

The bootstrap binaries don=E2=80=99t matter much, I think.  What does matte=
r is
to get =E2=80=98gcc-boot0=E2=80=99 (a fake cross-compiler) to target the ri=
ght ABI by
default.  I=E2=80=99m not sure how to do that, though.
