Replace obsolete AC_TRY_FOO with AC_FOO_IFELSE

Browse Source 
Autoconf made several macros obsolete including the AC_TRY_RUN in 2000
and since Autoconf 2.50:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2

These macros should be replaced with the current AC_FOO_IFELSE instead.

It is fairly safe to upgrade and take the recommendation advice of autoconf
upgrade manual since the upgrade should be compatible at least with PHP
versions 5.4 and up, on some systems even with PHP 5.3. PHP versions
from 5.4 to 7.1 require Autoconf 2.59+ and PHP 7.2+ require Autoconf
2.64+.

This patch was created with the help of the autoupdate script:
autoupdate config.m4
