BUILD: Makefile: improve detection of support for compiler warnings

Some compiler versions don't emit an error when facing an unknown
no-warning unless another error is reported, resulting in all -Wno-*
options being enabled by default and being reported as wrong with
build errors. Let's create a new "cc-nowarn" function to disable
warnings only after checking that the positive one is supported.
