NetBSD/distrib/sets/sets.subr
apb f7004b0cbc Whenever we try to parse the output from make, run make with the -B
flag.  This ensures that -j<N> isn't accidentally inherited from the
environment, because the "--- foo ---" headers printed with -j<N> would
interfere with parsing the output.

# If printf is not builtin, approximate it using echo,
# and hope there are no weird file names that cause
# some versions of echo to do the wrong thing.
# (Converting to this version of dirname speeded up the
# syspkgdeps script by an order of magnitude, from 68
# seconds to 6.3 seconds on one particular host.)
#
# Note that naive approximations for dirname
# using ${foo%/*} do not do the right thing in cases
# where the result should be "/" or ".".
