Agreed. I don't think the above change would be a good idea.

To my eye, the better way out here would seem to be leave gcc as is, 
configure to use ${prefix}/bin/as, but then enhance the cctools port (in 
some way to be discussed) to allow it to behaviour more along the lines 
of how the system /usr/bin/as does.
