You have to
./configure --with-precision=extended
to reproduce the FAIL. Also add the config.log so we can exclude that any
environment variables are influencing the configure. In principle, it would be
not too surprising if you can't reproduce it on PowerPC as it also does not
happen when -O0 is used and I would assume that optimizations for different
architectures are different.
Configure fails when I set FCFLAGS='-m32' with
