David Cole b7f3f7cdb6 Add fail regex to detect supported warning flags correctly. ...

On Apple's gcc, the compiler emits a warning such as "warning: command
line option "-Wno-deprecated" is valid for C++/ObjC++ but not for C"
when it is passed that flag on its command line.

When testing for that flag with a plain C file, we should report that
the flag is unsupported for C files. The new FAIL_REGEX option added
here produces this behavior.
