Subject: [PATCH] Run gcc supported flags test with -Werror

- On gcc versions supporting -fstack-protector, not all platforms
  support this feature, causing gcc to emit only a warning instead
  of an error. Which then causes warning-spew on every compiled file.
  Run all the supported flag tests with -Werror to turn the warnings
  into errors, there could be other similar cases besides stack protector.
- Patch originally from Arnaud Patard according to this Mandriva commit:
