Unfortunately, ffmpeg's hand-crafted configure script does not like the
--build flag. It wants --arch, but then it stupidly replaces x86_64 by
x86_32. Jon's perl -pie fix does the trick here.
OTOH, the -m64 doesn't seem to be necessary if compiled with the default
"gcc" (that is, gcc-4.2 with Fink's arch trickery). For gcc-4.2 to work,
the "warning: cast from pointer to integer of different size" has to be
patched away, too.
Since the maintainer seems to be busy, I have now committed a patched
version of ffmpeg.info. Please test.
