Field G. Van Zee 3f48c38164 Cosmetic fix to configure output in config.mk.
Details:
- Fixed configure so that MK_ENABLE_MEMKIND is assigned "no" when the
  option is disabled due to libmemkind not being present. This wasn't
  affecting anything since the one use of the variable (in common.mk)
  was formulated as "ifeq ($(MK_ENABLE_MEMKIND),yes)". That is, the
  variable being empty was effectively equivalent to it being set to
  "no".
- Comment updates to build/config.mk.in, common.mk.
