Hmm, I found an issue with this now:

The AC_PROVIDE_IFELSE call should be wrapped in
  [ ...

so that autoconf won't complain about undefined AC_PROG_GO in cases
where the won't call AC_PROG_GO and thus aclocal won't pull
in go.m4.  This is needed for old Autoconf versions only.

With that, things seem to work.
