  ok, i finally have a full build for qemux86/core-image-minimal.
things i did:

* wiped the old kernel tarball from my local source mirror -- not
  sure why that fixed the kernel issue but a fresh download seems
  to have done the trick.
* removed the above CPPFLAGS_append line from local.conf
* used khem's ncurses recipe
* left the two ASSUME_PROVIDED lines where they were, out of sheer
  laziness since they seem to work.

  enough excitement for one day ...
