Shea Levy ea7a559290 Add support for the new Go frontend to GCC 4.6.0.
This isn't as useful as it could be, since gcc-wrapper doesn't know about
the gccgo binary so there is no gccgo wrapper script. Since changing
gcc-wrapper would lead to a nearly full rebuild, I thing the change to
gcc-wrapper should go into stdenv-updates.
