From 7d3b0331d91a9f80bc4bcddea929a93b07b8ef91 Mon Sep 17 00:00:00 2001

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]
