Subject: [PATCH] Makefile.am: make sure autoheader run before autoconf

autoheader will update ../libtool-2.4.6/libltdl/config-h.in which
autoconf needs, so there comes a race sometimes as below:
 | configure.ac:45: error: required file 'config-h.in' not found
 | touch '../libtool-2.4.6/libltdl/config-h.in'

So make sure autoheader run before autoconf to avoid this race.

Upstream-Status: Submitted [libtool-patches@gnu.org maillist]
