The flac dependency was completely bogus. Flac isn't used at all.
FFTW is only used by tests, so we don't need to provide a packageconfig
for that.
ALSA is only used by example code that isn't part of the packaged files,
so even if ALSA is enabled, it doesn't affect the build result.
Nevertheless, I prefer to disable it explicitly to be extra sure.
--disable-alsa resulted in a warning about an unsupported configure
option, although by some magic it seemed to actually work as expected.
A patch is added to get rid of that warning.
