Building gcc for MIPS: mabi=64 and -mips3 instead of -mips4?

[Dave Williss]

Is there any way to build gcc (3.0.4) so that the mabi=64 libraries (MIPS)
are
built for -mips3 instead of -mips4?  The system libs (/usr/lib64) are all
mips3.

Second question:  Is it important that they match?  The linker gives a
warning
if they don't.

What's the minimum processor needed for -mips4?  The name seems to imply
R4000, but the gcc man page says r8000 is the default cpu-type.  Does this
mean it will issue instructions that can only be run on an r8000 or that it
will
just schedule for an r8000?
