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.

- https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Obsolete-Macros.html
- https://www.gnu.org/software/autoconf/manual/autoconf-2.59/autoconf.pdf
