# We want to run the build with only ${WORLDTMP} in $PATH to ensure we don't
# accidentally run tools that are incompatible but happen to be in $PATH.
# This is especially important when building on Linux/MacOS where many of the
# programs used during the build accept different flags or generate different
# output. On those platforms we only symlink the tools known to be compatible
# (e.g. basic utilities such as mkdir) into ${WORLDTMP} and build all others
# from the FreeBSD sources during the bootstrap-tools stage.

# basic commands: It is fine to use the host version for all of these even on
# Linux/MacOS since we only use flags that are supported by all of them.
