This and the other similar reports on current@ appear to be problems
with the xtoolchain ports, not the base build system, and probably
should have been reported to the port's maintainer, or on ports@. Or
perhaps it's some sort of usage error, I don't know anything about the
xtoolchain stuff. In any case, there doesn't seem to be anything wrong
with the base build using the supported build mechanisms.
