Some assembly routines don't work on Thumb as-is. For now
just disable these so the codecs compile.
Affected codecs:
- libflac
- libmad
- libspeex
- libtta
- libwavpack
A few DSP routines need to be disabled for the same reason:
- crossfeed_process
- crossfeed_meier_process
- resample_hermite
- filter_process
- sample_output_stereo

Annoyingly, this makes all of the '.S' files we compile get treated as
divided syntax, so we need to make the syntax in them explicit.
