  dnl Automake 1.11 provides the pkg*dir variables merely without AC_SUBST,
  dnl that is, only at the Makefile.am level.  AC_SUBST them, so that
  dnl gl_CONFIGMAKE can compute the final values at configure time.
  dnl Blindly assigning the value at configure time is OK, since configure
  dnl does not have --pkg*dir=... options.
