This is expected behaviour, because the patches fronm Buildroot are
*not* applied when using an override-srcdir. This is done on-purpose, on
the assumption that the content of override-srcdir is entirely managed
by the user, and because there is *no* way for Buildroot to know if the
patches we have would still apply.

So, the new "error" you reported is totally expected.

Thanks for testing! :-)

Yann E. MORIN.
