Replace obsolete AC_TRY_RUN with AC_RUN_IFELSE

Autoconf made several macros obsolete including the AC_TRY_RUN and 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_RUN_IFELSE instead.

This patch was created with the help of the autoupdate script.
