From 673ff5eb2cab14f4e2b21a90e32e787ea315b5a1 Mon Sep 17 00:00:00 2001
From: Daniel Stenberg <daniel@haxx.se>

Subject: Moved down the ares check again to the bottom of the script since it
 modified the compiler and link options so nothing can be tested for after
 this check, as the c-ares lib might not have been built yet!
