That would explain my results too.  I did a `make check' without a
preceding `make install'.

This is already done for `libio' and `libstdc++', but not for `gcc' and
`g++'.

I usually do `make install; make check'.  But after noticing the
SAVE_LLPATH in my make log, I wrongly concluded that things would work
without a `make install'.
