This patch syncs and bumps the minimum required version of Autoconf for the `phpize.m4` script and the main `configure.ac` from previously mixed 2.64 and 2.59 to 2.68. At the time of this writing Autoconf 2.63 is still the version on Centos 6, however by the PHP 7.3 release current systems out there should all have pretty much updated Autoconf versions to 2.64+ at least. Centos 7 already has Autoconf 2.69, for example. This provides more options to update and get current with the *nix build system and also avoids broken builds in certain cases as pointed out in the relevant discussion [1]. Additionally, phpize also already provides the `AX_CHECK_COMPILE_FLAG` Autoconf Archive m4 file that has Autoconf 2.64 minimum requirement. Autoconf 2.68 was released in 2010, 8 years ago, relative to this patch. [1] https://github.com/php/php-src/pull/3562
