From bdf523e6923f1e667055e947e71fc600549cefae Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sun, 20 Oct 2013 18:39:21 +0200 Subject: configure: Add config.status to recreate the current configuration The latest configure invocation was saved in config-host.mak and could be extracted from that file to recreate the configuration. Now it is saved in a new file config.status which can be directly executed to recreate the configuration. The file name and the comments were copied from GNU autoconf. Makefile now uses config.status, but also includes transitional code for the old mechanism.
