description:
Now that we know what sources are needed to build a given library, we need
the rules how to build those sources.  Generate makefiles defining ${COPTS},
${CPPFLAGS}, and ${SRCS} (== template).

Note that ${CPPFLAGS} is actually dfined as _CPPFLAGS like
        _CPPFLAGS.tmp___gcc_bcmp.c=-DL__gcc_bcmp
and used to generate wrapper files (e.g. tmp___gcc_bcmp.c).  Otherwise it's
automagically passed to ${CC} by bsd.*.mk.
