[webkit-gtk] webkitgtk-2.0.4 compilation fails

[Žan Doberšek]

Could you check whether the CFLAGS and CXXFLAGS in the generated
GNUmakefile contain the options you've additionally specified?

There are at least two ways of doing this:
- `cat GNUmakefile | grep "^CFLAGS"; cat GNUmakefile | grep "^CXXFLAGS"`,
- run `make V=1` and see that the compiler invocations are using the
specified options.
