Attention! This patch is of questionable use, since all it does for
me is to avoid errors when the rts is built on one system for the
creation of boot.tar.gz for another system, to create a hc file
bundle. So it maybe completely pointless, and if someone wants to
push it at all, please test a normal build (or ask others to test
it) on other systems (at least Linuxes, maybe other BSDs) first.
