crossgcc: Delete conflicting, stale symbolic link

If a previous build failed or the build dir is still around for other
reasons (e.g. buildgcc's `-t`) the symbolic link to our `bin` dir we
create there is also still around and can't be created again without
removing it first. Attempts to use `ln -f` also fail as the existing
destination is treated as directory and a new symbolic link would be
created inside.
