If you are using Yocto 2.1 or later, it's safer and easier to
construct BBMASK as set of space separated expressions rather than
trying to append to a single regex. e.g. in this case:

  BBMASK += "qemu_qoriq.bb"

There's no need to wipe out sstate or tmp to test this. If you try to
build a recipe which doesn't exist or is masked, you'll get an error
regardless of whether the recipe has been built previously.
