configure: when performing a compiler feature test for a -Wno-foo flag, attempt
to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of gcc, where it will silently accept an unknown -Wno-foo option, but will generate an error for a compile which uses -Wno-foo if that compile also triggers any warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174770 91177308-0d34-0410-b5e6-96231b3b80d8
