As far as the sequencer is concerned, this change should not be
necessary. I think (and your other findings seem to support that) there
is a problem with the configuration of this target architecture in base.
I guess there is a file missing somewhere but I have no clue what it
could be.

Sorry, I can't be more helpful.
