Upgrade deprecated AC_OUTPUT macro calls

Autoconf 2.50 made several changes to macro calls. These include also
arguments passed to AC_OUTPUT macro. The upgrading chapter in Autoconf
documentation include an example of using AC_OUTPUT with
AC_CONFIG_FILES and AC_CONFIG_COMMANDS:
- https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Obsolete-Macros.html

PHP 5.4 to 7.1 require Autoconf 2.59+, PHP 7.2+ require Autoconf 2.64+,
and PHP 7.2 phpize script requires Autoconf 2.59+ which are all greater
than above mentioned 2.50 version. Systems out there should well support
this by now.

This patch was created with the help of autoupdate script:
autoupdate <file>
