description:
A makeoptions `DEFWARNINGS', forcibly disabling all ${CC} warnings, is only
used by hpcmips's NULLCONF, which doesn't even build for other causes.

If some source doen't build and needs a workaround, that should be deal with
by modifying per-file ${CC} options (e.g. COPTS.foo.c+=-fno-xxx).  Let's not
use DEFWARNINGS any longer.
