freeswitch-stable: Fix mod_pocketsphinx build

- The builds currently fail with "undefined reference" errors. Fix that
  by turning off Pulseaudio support. Also turn of Jack support in case
  that gets detected in the future.
- aarch64 fails because this arch isn't recognized by the pocketsphinx
  build system. Fix that by running autoreconf in the pocketsphinx build
  dirs.
- Fix CFLAGS while we're here.
- Add dep on libsamplerate to mod_pocketsphinx. If it gets detected it
  will be linked against, there is no switch to prevent that.
