I'd like to know how to pass arguments to `configure' when attempting
to compile gcc-3.3.3.  Specifically, I'd like to run this command:

  configure --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld --disable-nls

I would imagine that these options can be set in
`/usr/pkg/etc/mk.conf' though I don't kow how.  If someone would
either point to the location where this is documented or provide me
with the recipe I would be most appreciative.
