Use return instead of exit() in configure
Using exit() requires stdlib.h, which is not included. Use return instead. Also add return type for main(). Reviewed-by: Heikki Linnakangas <hlinnaka@iki.fi> Reviewed-by: Thomas Munro <thomas.munro@enterprisedb.com> Backpatched because Apple macOS 10.16/11 (Big Sur) compiler makes calling undeclared functions an error, so these configure tests would fail.
