I'm afraid that's true as well.  From the NEWS file:

** @top_builddir@ is now a dir name: it is always nonempty and doesn't have
  a trailing slash.  Similar change will be made to ac_top_builddir in a
  future release; the old style value, which matches (../)*, is (and will
  continue to be) available as ac_top_build_prefix.
