 This comment is redundant.

 Use = instead of := and put spaces around it.

 Also, the quoting is really redundant. The original comment said "Quotes
are needed for spaces et al in path components", but since that was only
done for TARGET_PATH and not for HOST_PATH it didn't work in the first
place. In addition, we also don't add quotes around the other uses of
HOST_DIR etc., so it's just $(PATH) itself that we're protecting. If you
do keep the quotes, at least copy the comment.

 This comment is no longer in the right place.
