The imake generated makefiles don't know about COPTS...

There's a list of things to set in "host.def" in the README file in
the same directory, in particular DefaultCCOptions. Nobody actually
does that...

I expect when lukem is finished with the src/x11 stuff, you'll be able
to do that the ordinary way, with COPTS or CPUFLAGS. In the meantime,

    make build CCOPTIONS='-foo' -CXXOPTIONS='-foo'

works for me. CCOPTIONS (== DefaultCCOptions) is empty on all but a
few NetBSD ports, and I doubt that the options that are set on the
others are still needed to build. You need to override on the command
line (or add it to MAKEFLAGS in the environment), because it is set
unconditionally in the makefiles, even if to empty.
