| Subject: [PATCH] Fix libtool detection |
| |
| Upstream-Status: pending |
| |
| Use LT_INIT instead of the deprecated AC_PROG_LIBTOOL to detect libtool, so it |
| can work with our libtoolize and libtool. |
| |
| Simplify the detection of ltdl. It will find the ltdl from the sysroot; the |
| switch --with-system-libltdl is no longer needed. The code is copied from |
| pulseaudio configure.ac, together with the comment paragraph. |
| |
| Also patch autogen.sh so it uses autoreconf, which handles libtoolize better. |
