FYI: master now depends on unreleased Autoconf

[Ralf Wildenhues]

I'm about to apply the fast install patch.  Since it needs the fixed
AC_PROG_INSTALL, git master of Automake will depend on an unreleased
Autoconf version, which I'm putting in with the patch below (diffs of
generated files not shown, as always).

With respect to committing generated files, I will try to stick to this
policy: Whenever I commit changes that change generated files, I will
use an up to date git Autoconf to rebuild it.  

When the next Autoconf version (alpha, beta, or stable) is released,
then that will be used (and sticked to, unless needed otherwise) and
the version jumping will stop again.

Cheers, and sorry for any inconveniences,
Ralf

    Require unreleased Autoconf for fixed AC_PROG_INSTALL.
    
    * m4/init.m4 (AM_INIT_AUTOMAKE): Bump AC_PREREQ to 2.61-341,
    regenerate files.
    * configure.ac: Also require Autoconf 2.61-341, to catch
    failure early and provide a sensible error message.
