Patchwork Speed up makefile processing a bit

Hi,

following patch reduces time make -n oldconfig from ~5 to ~0.5 seconds
on mingw, by not parsing all the Makefile.incs when they're not in use.
Same for the other config targets and distclean.

It also optimizes rm -rf and mkdir -p sequences a bit: No need to delete
all object files manually, just to run rm -rf $(obj) afterwards.

This starts getting semi comprehensible... maybe a (short) comment why
this is done would be nice..

Also, does %config or *config work instead of mentioning all configs?

Done.

Yes, I didn't want to risk that we add some %config target that needs
$(obj), which then fails.

But I guess that won't happen, so done.
