Right now this is a noop in the former case and a noop in the latter
case unless lang/gcc44 has been installed explicitly.
This puts a bit more emphasis on standardizing on a canonical version
"current" GCC and makes it easier to update that canonical version
by changing the default in Mk/bsd.gcc.mk and updating the lang/gcc port.
That is, USE_GCC=yes means "use a decent/modern version of GCC" without
having to worry about details.
