Good. While we are on it, here are things I'd like to see in the new
`traditional 64bit MIPS ELF ABI':
1. Make gp callee-saved.
2. Use RELA relocation if all possible.
3. Use relocations in the SGI 64bit ABI when make senses to us.
4. Drop support for the MIPS/SGI quickstart.
5. Add support for the glibc prelink.
#1 is a gcc only issue. I think the change to gcc is minimum. That is
we make sure that we don't use o64 for gcc. #2, #3, #4 and #5 will
affect binutils.
