Subject: allow re-building of individual "configure" files
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=59e2543c381df85dfd363a61cc4f41e933b6cdbc;p=thirdparty%2Ffreeradius-server.git

allow re-building of individual "configure" files

and work around autoconf crap, where it touches the inputs,
so that the outputs are almost always out of date.
