I haven't seen this exact problem, but I did
bring up a toolchain on sh4, and I had similar
problems.  I ended up debugging them in two ways:
1) by running the glibc and gcc regression tests
(see crosstest-howto), and
2) by starting with a working target environment
from some other source (e.g. montavista), and creating a
chroot jail containing my new environment.  I
then inserted print statements (well, write syscalls) into glibc etc.
until I tracked down the problem.

I poked around a bit, and found some posts that might be related:

Any chance one of the errors was
arch/mips/kernel/time.c:278: error: unknown register name `accum' in `asm'
That's what stops linux-2.6.8; see
