PHP buildconf

A wrapper around the autoconf and autoheader that generate files for building
PHP on *nix systems (configure, main/php_config.h.in, aclocal.m4...). 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:
  --force         Clean cache and overwrite configure files.
  --debug         Display warnings emitted by Autoconf.
  -h, --help      Display this help.

ENVIRONMENT:
  The following optional variables are supported:

  MAKE            Overrides the path to make tool.
                  MAKE=/path/to/make ./buildconf
  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
