Fine with me.

This change makes sense as the features supported by the gcc and clang
compilers shipped in ports are almost homogenous at the moment; in the
past there were differences as not all gcc4* shipped gfortran or gcj.
However, I don't expect the situation to change in the near future.

One minor stylistic comment, when using regexp and you don't care about
the whole match, it's convention in the Tcl community to use -> as
variable name:

 regexp {macports-clang-(.*)\.(.*)} ${configure.compiler} -> major minor
