Upgrade deprecated AC_OUTPUT macro call

Autoconf 2.50 made several changes to macro calls. These include also
arguments passed to AC_OUTPUT macro. The upgrading chapter in Autoconf
documentation includes 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

Systems out there should be well supported by now.

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