From c8e39d6d298f921b8b510bb88bc210fb30f0bd10 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Mon, 7 Nov 2011 22:28:40 +0100 Subject: configure: use autoconf to generate configure Create configure.ac, an autoconf script to generate ./configure This will be needed by a subsequent patch to properly handle --build and --host, and more tests, when the kconfig stuff will be installed pre-built.
