Subject: Fix symlinking to multiarch tools on Cygwin

On cygwin, creating both "foo.exe" and "foo" results in 'ln -sf'
returning an error ("File exists"). However, ln silently removes
the "foo.exe" in this case, so an attempt to re-run the same command
manually then succeeds.

Hence, make binutils.sh also create symlinks with .exe prefix,
using the new & shiny routine.
