Unfortunately the error handling for that is completely missing in
ISAR. This only becomes visible when building a multiconfig target but
forgetting to set the machine and distro in the kas project config
(which is anyways just needed for the initial bitbake parsing).
Not much we can do here, except for putting the ISAR ML in CC.

PS: I just saw that the isar-init-build-env puts in "qemuarm" as
default. What...!
