[OE-core] [PATCH 0/1][v3] license.bbclass parsing changes rebased sans debug

[Elizabeth Flanagan]

In this case, elfutils should probably be changes as well as license.bbclass. As do_populate_lic is looking for valid 
python to make a syntax tree from, this will fail. Solution:

1. Fix license.bbclass to check LICENSE and massage it a bit more.
2. Fix elfutils to be GPLv2* (unless it's the GCC exception. I haven't read the license yet).

I'll poke around this today.
