[gcc] Enable gcc-go frontend and libraries. Contributes to JB#62642
Browse files Browse the repository at this point in the history 
Since we don't use update-alternatives, make gcc-go always provide
symlinks to go and gofmt. Checks that such binaries don't yet exist.
This makes it possible to have gcc-go and go installed at the same time.
This assumes that Go packages them as regular files, not symlinks.
