Title: GCC 4.7.2 and Dependency Downloading

I just copied the 4.7.0 patches for 4.7.2, and changed the GCC version.

There was a bug with mpfr being downloaded the way you were doing it where the header files were not getting installed to `$SRC/gcc/mpfr`. They were instead being put in `$SRC/gcc/mpfr/src` and the compile was looking for them in the first spot. As it turns out, this is probably due to the version of mpfr that was being used. To make sure we're using supported versions of the library dependencies, I switched the dependency downloading over to GCC's `config/download_dependencies` script.

With the dependencies script doing the downloading, you should be able to reproduce the ucontext.h libgo compile errors by just adding go to the `--enable-languages` line in the build script and then running a `sudo make install`.
