Interesting. I built it (along with 22 others) today and it worked
using gcc 4.2.1 and binutils 2.18 on x86_64 to build a 4.2.1 criss
cross-compiler on top of the inhibit_libc check for linux-unwind.h I
posted yesterday. I need to rework that one a bit,
but it got alpha, sparc, and several others building for me. The one
liner LIMITS_H_TEST got cris-gcc building for me. It is probably not
ready for prime time either, but it works for me.
I had a similar looking ICE on v850 which was the only one I have not
gotten to work yet although ia64 comes and goes, I'm not sure exactly
why yet. I started to reduce the list of things I'm --disabling or
doing --without and now I have yet another similar looking error in frv
that was not there earlier today. I looked into what I would need for a
bug report, but time for judo class rolled around and I left work before
I made any real progress on it. Not much difference to the config
commands. I moved the --enable-languages up a bit and got rid of
--disable-checking. The --with-sysroot and --with-newlib were already
commented out and ignored earlier. Something is definitely rotten.
Here is the config that produced criss-gcc and frv-gcc but got an ice
building v850-gcc

Segher - If remember right, cris was one of the targets that did not
build for you. This might help.
No idea if it would help or not -- it currently dies with
an ICE while building __mulvdi3:
