Fix Autoconf check for development versions (#11532)
When Autoconf version includes also development patch character (for
example, 2.72c), such as in unreleased Autoconf versions, this now
sets proper number for checking minimum required Autoconf version.

PHP buildconf
A wrapper around the autoconf and autoheader that generate files for building
PHP on *nix systems (configure and main/php_config.h.in). The configure script
is used to customize the PHP build based on the provided options and system. PHP
releases downloaded from PHP.net already include the configure script so
installing Autoconf and running buildconf is not needed. For the PHP sources
from the Git repository, buildconf is used for generating a new configure script
and required files.
SYNOPSIS:
buildconf [<options>]
OPTIONS:
-f, --force Regenerate configure files in PHP release packages.
--debug Display warnings emitted by Autoconf.
-h, --help Display this help.
ENVIRONMENT:
The following optional variables are supported:
PHP_AUTOCONF Overrides the path to autoconf tool.
PHP_AUTOCONF=/path/to/autoconf ./buildconf
PHP_AUTOHEADER Overrides the path to autoheader tool.
PHP_AUTOHEADER=/path/to/autoheader ./buildconf
