+Subject: [PATCH] avoid running automake/autoconf --version
+
+The libtool would be very slow if run "automake/autoconf --version", for
+example, when compile xz (make -j1):
+
+before patched: 19s
+after patched:  11s
+
+Use plain text to instead of running them.

+Upstream-Status: Pending [Report to libtool community]
