I was unclear; I meant "you can't pass per-target (${PROG} / ${LIB}) parameters
to ${CC} directly".

And yes, it's actually possible to append ${CPPFLAGS.foo} to
${CPPFLAGS.foo_src_a.c}, ${CPPFLAGS.foo_src_b.c}, ... by using .for.  I don't
think that is worth bothering.  I can also think of odd situations where you
share one source among multiple targets:

        PROGS=foo bar
        SRCS.foo=foo.c common.c
        SRCS.bar=bar.c common.c
        CPPFLAGS.foo=-Dfoo
        CPPFLAGS.bar=-Dbar

Think how common.o will be built...
