Jessica Clarke 1a9b1c367f release: Add support for building on non-FreeBSD
This requires two sets of changes. Firstly, for non-FreeBSD, we do not
know where tools are in PATH (and it is likely that some are not in
system directories and have been built as bootstrap tools during the
build), so we should leave PATH alone and trust the user. Secondly,
makefs needs a master.passwd for building images from a METALOG file, so
pass the directory in the image tree to makefs's -N option in order to
pick up a valid FreeBSD master.passwd; this is unnecessary on FreeBSD
(except in the edge case of building an image that refers to users or
groups not present in the host's database, which is unlikely but
technically possible) but harmless so can be done unconditionally.

#
# This script is used by release/Makefile to build the (optional) ISO images
# for a FreeBSD release. It is considered architecture dependent since each
# platform has a slightly unique way of making bootable CDs. This script
# is also allowed to generate any number of images since that is more of
# publishing decision than anything else.
#
# Usage:
#
# mkisoimages.sh [-b] image-label image-name base-bits-dir [extra-bits-dir]
#
# Where -b is passed if the ISO image should be made "bootable" by
# whatever standards this architecture supports (may be unsupported),
# image-label is the ISO image label, image-name is the filename of the
# resulting ISO image, base-bits-dir contains the image contents and
# extra-bits-dir, if provided, contains additional files to be merged
# into base-bits-dir as part of making the image.
