Oops, I was sloppy.  I should have written (binary) 240; I just get so used
to that hex prefix...

I'm going to digest what you sent, but in the meantime, can you do one
thing?  Run a configure/build based on a clean (unmodified) source tree.  I
want to see what happens on your system without all the strace/sh -x

I have found that strace interferes with expr, such that the return value of
the pipeline which contains strace is always 0, triggering the failure in
the build scripts looking for a non-zero exit code to expr in certain places
(such as ours).
