There are additional cases of this potential issue in the tree. In
most cases I examined the target invokes tools that are expected to
exist on the build host (such as sed or awk) so should not be a
problem in practice. There are some cases (gensnmptree, make-roken)
that we may want to revisit as part of a more holistic build
infrastructure project.
