Do I need to run a complete build first? When I run that make target

Hmmmm, you're right, it doesn't work. Sounds like a bug. Try running
"make all-stage1" (I had to run it a couple of times for some reason)
and then run "make configure-stage2-gcc" (which I also had to run
twice). You should wind up with a prev-gcc directory and a gcc
directory. The gcc directory is what will in the end become stage2-gcc.
Should I file a bug about the multiple runs being necessary? I poked
around a bit and it seemed that different -j options results in a
different number of tries. That being said, even -j1 required multiple
tries. (This may be a symptom of one of the issues that causes my builds
to fail spectacularly every blue moon when doing -jN>6.)
Beyond that, I now have the binary generated by prev-gcc/xgcc and it does
indeed crash:
Starting program: /home/matt/src/gcc-trunk/obj/conftest

Is it tripping over a bug in the system compiler (again, GCC 4.6.1-based
default from Ubuntu 11.10)?
Let me know how you'd like me to proceed.
Thanks!
