kbuild: Add extra gcc checks
Add a 'W=1' Makefile switch which adds additional checking per build
object.
The idea behind this option is targeted at developers who, in the
process of writing their code, want to do the occasional
make W=1 [target.o]
and let gcc do more extensive code checking for them. Then, they
could eyeball the output for valid gcc warnings about various
bugs/discrepancies which are not reported during the normal build
process.
For more background information and a use case, read through this
