If we keep BACKPORT_BPAUTO as prefix on compat/Kconfig for auto backport
stuff we'll end up with BACKPORT_BACKPORT_BPAUTO, while technically correct
as you have pointed out, I find it personally superfluous. If we however
only use BPAUTO_ prefix on the compat/Kconfig we'll end up with BACKPORT_BPAUTO.
Its subjective then, but I was opting in to prefer to just keep BPAUTO_ prefix
with the resulting CPTCFG_BPAUTO for packaging and CONFIG_BACKPORT_BPAUTO for
integration for these, if you however feel its best to double the BACKPORT
prefix that's fine too, it just seemed odd (although I realize correct).

To do what I just described I think you're right will try removing that,
testing that now. The other case that I ran into issues was the backport
versioning variables but I have solved that through other non intrusive means
to packaging (just use the C define with CPTCFG_ prefix, keeping the original
Makefile variables) which will be part of my next respin.

We still do need to decide if we want double BACKPORT_ prefix for BPAUTO
though, that remains subjective and I don't feel strongly about any way
we go.
