yes, it is intentional and documented in the NEWS file:

** @top_builddir@ is now a dir name: it is always nonempty and
   doesn't have a trailing slash.

Previously, @top_builddir@ differed from $(top_builddir) in
Automake-generated makefiles; this change makes them consistent.

If you are using it in Automake-generated makefiles, you could
perhaps use `$(top_builddir)' instead.  With this notation, you get the
same value with all versions of Autoconf/Automake, including the
upcoming ones.

Have a nice day,
