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] Cc: Josh Boyer <jwboyer@linux.vnet.ibm.com> Signed-off-by: Segher Boessenkool <segher@kernel.crashing.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
