[OE-core] could OE maybe point out when a recipe has upper case letters in it?

[Robert P. J. Day]

  in a fit of silliness, i created some packagegroup recipes and,
without thinking, had the string "OE" as part of the recipe file name,
and was baffled when i kept getting errors that trying to add that
packagegroup to my image was failing due to an "empty" package.

  it was doubly mystifying since i had been using wind river linux
where the packagegroup names contained the string "WRL" and that
worked just fine. changing the "OE" to "oe" appears to have solved the
problem.

  thoughts? why "WRL" worked with wind river linux, and "OE" failed
with a poky build? i don't plan on making that mistake again.
