build: fix detecting support for -Wno-* compiler flags

Since GCC 4.4, gcc does not warn about unknown -Wno-* flags. At
least, it does not warning unless another warning is raised as well
(https://gcc.gnu.org/wiki/FAQ#wnowarning).

We didn't notice up to now, because we only tested flags that GCC
actually supports.

Hack around this, by checking for the -W* counterpart instead.
