I'm struggling to figure out how the code is doing this. The most
interesting piece here is:

classes=[None, 'gitpkgv', 'autotools']

and I cannot get a recipe locally to do this. classes is basically set
from BBConfHandler and its a relatively simple codepath. This would
imply the gitpkgv class is doing an "inherit autotools"?

Can you show how you're using gitpkgv in your code and what the bbclass
contains? I have the version from meta-oe but I'm failing to reproduce
or explain how this would get into there...

Are you doing anything interesting with EXPORT_FUNCTIONS anywhere in
your code?

Its very odd and any more information about your configuration would be
helpful in reproducing/debugging this.

Cheers,
