Re: [PATCH v2] build: do not automatically reconfigure unless configure.ac changed

Starting with v1.7.12-rc0~4^2 (build: reconfigure automatically if
configure.ac changes, 2012-07-19), configure is automatically run
every time the "configure" script changes.  In particular, that
means configure is automatically rerun whenever the version number
changes (which changes the configure script to support "./configure
--helpe"), which makes bisecting painfully slow.

The intent was to make the reconfiguration process only trigger for
changes to configure.ac's logic.  Tweak the Makefile rule to match
that intent by depending on configure.ac instead of configure.

It seems I am late to the party. But FWIW, this looks the most sane to
me of the patches posted in this thread.
