Subject: build: ship autobuild.m4, to reduce bootstrap requirement
X-Git-Tag: v2.4~8
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=31221926db25f9d8b34ac5d79412355896f3c70d;p=thirdparty%2Flibtool.git

build: ship autobuild.m4, to reduce bootstrap requirement

Shipping a copy of autobuild.m4 makes it so that users need not
pre-install autobuild just for aclocal to find the macro AB_INIT.

* libltdl/m4/.gitignore: Drop autobuild.m4.
* libltdl/m4/autobuild.m4: New file, copied from autobuild.
* configure.ac (AB_INIT): Unconditionally call it.
