Subject: [PATCH] allow newer autoconf versions

Spidermonkey is hardcoded to use Autoconf 2.13, which is from 1999!
The reasoning behind using 2.13 is because newer versions of Autoconf at the
time did not work correctly with the custom m4 macros in the source code.
However: Because we are building just the spidermonkey engine instead of the
entire firefox package, and we are using a tarball with a pre-setup
old-configure file, there is no need for the old version of autoconf.
