Same thing happens on 2.2.7-r1 which is currently stable, so I prepared patch on 2.2.7-r1, but also tested it on 2.2.7-r102 (mentioned in bug report). Please review if that makes sense, but seems to be working.

Issue: implicit function declaration for exit function.
Reason: Missing header which contains exit function inside configure file.
Solution: Add #include <stdlib.h>.
