Create a single combined module for spkr_pcppi and spkr_audio, and
build it for all architectures.

By doing this, we can handle pcppi, audio, or both attachments with
non-built-in modules.

XXX Still to do: the module currently cannot be unloaded, and the
XXX spkr device(s) currently cannot be detached. (Really, two
XXX sides of the same problem.)

Revert to previous. Add PCPPISPEAKER flag to fix build.

Fix building of the spkr module. The module now is the synthesized speaker.
