Subject: [PATCH] Allow defining of uname value for reproducible builds

Extend configure.ac to accept PHP_UNAME as env variable to set the value of the
PHP_UNAME define in a reproducible manner. This allows distributions to set a
fixed value for php_uname and keep the default behaviour if PHP_UNAME is not
set.

Motivation: https://reproducible-builds.org/
