[PATCH] kbuild: add defconfig targets to make help

From: Sam Ravnborg <sam@ravnborg.org>

List all entries in arch/$(ARCH)/configs/*_defconfig when doing 'make
help'.

Results in output like this (ppc64 as example):

  g5_defconfig             - Build for g5
  pSeries_defconfig        - Build for pSeries

The implementation is generic and enables this for all users of _defconfig.
