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. Signed-off-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: Fam Zheng <famz@redhat.com>
