Thanks for the detail - including this information in the justification
would be a good idea so anyone looking at the commit log can understand
why it was necessary.

I was thinking so, but I see Saul raised it as an issue with V2, so
please disregard this comment, it's fine.
I'd like to see a blurb added to the commit message stating the bit
about gcc not having support in some distributions (debian/ubuntu do
have it for example, but later versions require the compat package or
some such). The fact that some don't is enough though, and your solution
is cleaner and more consistent with bitbake recipe conventions anyway.
Thanks for keeping at it, this is a good improvement.
