I suppose this is a desirable thing to support, since outside
pkgsrc-land, one is usually able to set CC to something like the above
and have things Just Work. this desire might rule out adding something
new like PKGSRC_CFLAGS ...

right, I'd forgotten about this...

I've been trying to think of ways that we could possibly remove the
definition of CC/CXX (and others) from sys.mk, but that may pose a
problem with using bmake for non-pkgsrc purposes.

grant.
