Actually, this is the first problem I saw, but I've waited until the final
toolchain was completed before I mention it.

On x86_64, with glibc-2.12.1 and otherwise the 20100803 book, in
pass 2 glibc the build failed in libgomp with

configure: error: unsupported system, cannot find sizeof (omp_lock_t)
make[1]: *** [configure-target-libgomp] Error 1

Looking at config.log, there was an error in the relevant test,
failed to open libgcc_s.so.1 : No such file or directory

 My previous logs are defective (I'd accidentally overwritten pass 1
with pass 2), but ISTR we never created libgcc_s in gcc pass 1.
So, I'm tentatively labelling this as a gcc-4.5.1 problem.  The fix
is what we do in pass 1 : --disable-libgomp.

 Since Matt didn't mention this, I guess it's only needed on x86_64.

ĸen (still in chapter 6 automake, and dreading what make-3.82 will
to to the things I build for my desktop :)
