  # We have a patch that affects libtool.m4, which triggers an autoreconf
  # in the build step. Normally we would set AUTORECONF = YES, but this
  # doesn't work for host-libtool because that creates a circular
  # dependency. Instead, touch the generated files so autoreconf is not
  # triggered in the build step. Note that aclocal.m4 has to be touched
  # first since the rest depends on it. Note that we don't need the changes
  # in libtool.m4 in our configure script, because we're not actually
  # running it on the target.
  # For the target, we would normally be able to use AUTORECONF, but it
  # fails on libltdl/Makefile.inc. Rather than trying to fix that failure,
  # just use the same hack as on the host.
