You run into the same problem i have. We look at that bug in an
extremadura, ES meeting during September, but we could not find a fix
for it. It seems that it could be away arround turning off multiarch
support (that is done in the debian/ from source gcc) HINT: Grep for
DEB_CROSS

I still have more hope than time to work on it to have that bug fixed.
It is still pending for all multiarch architectures, but arm nor
armel. Currently i am focusing on building infrastructure for
toolchains and try to fix all these problems we have with versions in
the repository. It can take a while until everything works smoothly.

ABI is the one default by Debian, you could just patch, again, debian/
dir to try to change ABI, unknown problems within toolchain might
appear, but i think it would be nice to give it a try.
Currently, we have to think a generic way arround this part also, the
focus would be supporting many different ABI for different
architectures, using some diversion magic with libgcc. Help is welcome
towards this PoC.

That is more in the rootfs land, i believe there is some docs in the
web[1] and right now it is an experimental idea to support machine
specific configs, IIRC.
I have to warn you that it is a long road before you can run crush
into a sparc machine.
