Replace obsolete AC_TRY_FOO with AC_FOO_IFELSE

Autoconf 2.50 released in 2001 made several macros obsolete including
the AC_TRY_RUN, AC_TRY_COMPILE and AC_TRY_LINK:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2

These macros should be replaced with the current AC_FOO_IFELSE instead:
- AC_TRY_RUN with AC_RUN_IFELSE and AC_LANG_SOURCE
- AC_TRY_LINK with AC_LINK_IFELSE and AC_LANG_PROGRAM
- AC_TRY_COMPILE with AC_COMPILE_IFELSE and AC_LANG_PROGRAM

PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version therefore systems
should be well supported by now.

This patch was created with the help of autoupdate script:
