codecs: disable incompatible ARM assembly for Cortex-M

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
