65# programs used during the build accept different flags or generate different
66# output. On those platforms we only symlink the tools known to be compatible
67# (e.g. basic utilities such as mkdir) into ${WORLDTMP} and build all others
68# from the FreeBSD sources during the bootstrap-tools stage.
