Subject: build: make sure autoheader run before autoconf
X-Git-Tag: v2.5.0~66
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e7dc729dd27b367905cd0ce52b5466d91537857a;p=thirdparty%2Flibtool.git

build: 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.

* Makefile.am: Have $(lt_configure) depend on $(lt_config_h_in).
