Mmmm, yes, you're kinda stuck, I've already had a look, and it's not
possible to have options working including port.options and also be able to
change stuff after it.
Though, USE_GCC=yes will never use the old base gcc, but always lang/gcc
(well, the one defined in bsd.default-versions, which if left alone is
lang/gcc), USE_GCC=any will use gcc from base though, but I'm not sure you
can have a good reason to use it.
