It looks like you are running ./configure. That should work in
principle but is generally ill-advised. I recommend doing a fresh
checkout and running configure in a different directory.
That said, your specific problem seems to be gas/config.cache is not
being removed. I don't know why, as "make distclean" in the gas
directory should remove it. Presumably the top level "make distclean"
is not descending into the gas directory, but again I don't know why.
