Fix -Wno-unknown-warning support detection
Ref: https://sourceware.org/ml/gdb/2015-12/msg00024.html
We have code in configure.ac that tries to detect whether the compiler
supports each warning and suppress it if not, but that doesn't work
with "-Wno-" options, because gcc doesn't error out for
-Wno-unknown-warning unless other diagnostics are being produced.
See https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html.
Handle this by checking whether -Wfoo works when we actually want
-Wno-foo.
gdb/ChangeLog:

* configure.ac (compiler warning flags): When testing a
-Wno-foo option, check whether -Wfoo works instead.
* configure: Regenerate.
