bug#8342: 24.0.50; Emacs HEAD cannot build with OS X standard autoconf

[Steve Purcell]

The latest Apple developer tools (XCode 3.2.6) provide autoconf version
2.61. Since 'configure' was removed from emacs bzr, it cannot be
regenerated on this platform without autoconf >= 2.6.5, i.e. overriding
Apple's standard autotools, which is widely deprecated.

IMHO, it should continue to be possible to build emacs without doing so,
as has always been the case.

% ./configure --with-ns
zsh: no such file or directory: ./configure
% autoreconf
configure.in:24: error: Autoconf version 2.65 or higher is required
configure.in:24: the top level
autom4te: /usr/bin/gm4 failed with exit status: 63
aclocal: /usr/bin/autom4te failed with exit status: 63
autoreconf: aclocal failed with exit status: 63
