yes, known problem on powerpc. we play tricks on s390, sparc, powerpc
and i386, see disable-configure-run-check.dpatch. That used to work on
all four architectures to build the biarch compiler, but stopped
working on powerpc.  If you want to have a look, please go ahead.

You'll notice different test results as well, when uploading packages
built on a 32bit machine, missing the 64bit test results.

uploaded gnat-4.1 for powerpc now.
