It errors during parsing which stops the build going any further. It
doesn't really matter whether its a bb.fatal or bb.error, both would
have the same effect here which is to stop the build at parse time.

It used to be a bb.warn(), people ignored it. Personally I'd like to
drop the thing entirely but people wanted an error so we have that now
for this release. We're not changing it back to a warn().
