Not an option for us on fink since the same packaging script has to both list
the built shared libraries
and run on both non-EMT64 and EMT64 processors. For now, I am forced to just
short circuit the
test locally with the hack...

so that libquadmath can be built like all the other 64-bit binaries regardless
of EMT64 support.
