The problem happens before that, it's when glibc is trying to generate some
headers using the compiler as a way to extract info from the source.
I got around the previous problem by disabling linuxthreads and sanity checks
when configuring glibc the first time (the bootstrap compiler doesn't need
threads, does it?), but ran into another problem.

"make install-headers" fails with

gawk -f ../sysdeps/gnu/errlist.awk ../manual/errno.texi > ../sysdeps/gnu/errlist.c-tmp
chmod a-w ../sysdeps/gnu/errlist.c-tmp
mv -f ../sysdeps/gnu/errlist.c-tmp ../sysdeps/gnu/errlist.c

It seems to be generating errlist-compat.c, which is rather annoying, since
we only asked it to generate headers.
This appears to be a bug in glibc's Makefile's 'install-headers' target.
I suspect it could be worked around by doing
   make sysdeps/gnu/errlist.c
   touch stdio-common/errlist-compat.c
before doing make install-headers, but that workaround pains me...
I'm trying it out now, but won't know how it turns out for a bit yet
(somebody appears to have unplugged an important network cable,
so I can't see how the build's going :-)
