Yes, in 99% of the cases, you want VAR_append_foo and not VAR_foo_append.
VAR_foo_append makes sense when you want to append to VAR_foo which is a
way to override completely VAR for builds matching the foo override.
This happens in kernel-yocto recipes where branches and defconfigs are
different per machine for example.
The sneaky thing about VAR_foo_append is that it creates VAR_foo even if
it didn't exist beforehand, meaning you though you *appended* something
to VAR while you actually replaced VAR entirely with what VAR_foo_append
is set too.
