I use some hacks to make the resulting configure script work even if
autoconf can't find pkg.m4.  Basically I just use "m4_define_default" to
define stub versions of the PKG_... macros:

   # Check for pkg-config program, used for configuring some libraries.
   #
   m4_define_default([PKG_PROG_PKG_CONFIG],
     [AC_MSG_CHECKING([pkg-config])
      AC_MSG_RESULT([no])])

   PKG_PROG_PKG_CONFIG

   # If the pkg-config autoconf support isn't installed, define its
   # autoconf macro to disable any packages depending on it.
   #
   m4_define_default([PKG_CHECK_MODULES],
     [AC_MSG_CHECKING([$1])
      AC_MSG_RESULT([no])
      $4])

   ... etc
   PKG_CHECK_MODULES([libpng], [libpng], [have_libpng=yes], [:])
   ... etc
