Hi,
When I specify subdir-ccflags in a Makefile, e.g. net/Makefile, but then
build using M=net/wireless/, kbuild doesn't seem to pick it up.
To me, that seems like a bug, but to my untrained eye it would appear to
be quite hard to fix. Thoughts?

For M=, this can't be fixed, because make M=$dir means "build external
module which resides in $dir" (so the parent directories have no
relevance). But even for 'make dir/subdir/' it would be hard to fix :-/.

Agree with Michal on this one. This is not easy to fix at all.
