Fix build problem with BSD Make.

* contrib/sboxes/sboxes.am:

* tmac/tmac.am: Fix portability problem involving BSD Make.  Define
  `*_builddir` macros without interpolating `top_builddir`.  groff does
  not use recursive make; all file specifications are resolved relative
  to the top of the build tree, so the interpolation is unnecessary, and
  with BSD Make it causes spurious failures because that implementation
  uses strings, not file identities, as the nodes of its dependency
  graph.  So if you ask for "foo" to be built but have only a rule for a
  target named "./foo", BSD Make fails, whereas GNU Make does not.
