# 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.
