kbuild: show defconfig subdirs in make help
PowerPC will start moving board defconfigs into subarch-specific
subdirs soon. "make help" currently does not look in subdirs to
find the defconfigs to show. This is partially a good thing,
since there are way too many defconfigs for one list.
This patch makes the main "make help" display something like
help-40x - Show 40x-specific targets
help-44x - Show 44x-specific targets
help-boards - Show all of the above
and wires up stuff so those new help-* commands actually work.
[sam: fixed it up to display x86 defconfigs too]
