They should, at the very least, be using ${HOST_CC} and ${HOST_CFLAGS},
not assuming "cc" and "-O".  Are you sure they don't do that?

I think we should work towards treating them all as tools.

Even without that sort of wrapper framework, some imaginative
use "grep cc | grep -v WHATEVERFLAGS"  could probably find evidence in the
build log.

HOST_CC and HOST_CFLAGS (and several related variables) are defined in
bsd.sys.mk, or can be overridden in /etc/mk.conf.
