Conditional platform inclusion cleanups.

We only compile files that are appropriate for the platform.  (We
still have guards in place, to allow for a future single .C file
to be built from all the sources.)  We also remove the subsystem defines;
if a new platform needs to deviate from POSIX in ways beyond what we
intended here, then that platform should just copy those parts into
a new platform directory, rather than cross including portions from
POSIX.
