Anyone having a problem with cross building arm* tools on current?

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

With a very recent checkout of NetBSD-current I am seeing a failure to
build tools on arm6, aarch64 (and probably arm7), build.sh bombs out:

dependall-dtc ===> .	(with: dependall-makestrs dependall-makekeys
dependall-cvslatest)
dependall ===> makestrs
nbmake[2]: nbmake[2]: don't know how to make makestrs.c. Stop

nbmake[2]: stopped in /usr/src/tools/makestrs

*** Failed target:  dependall-makestrs
*** Failed command: _makedirtarget() { dir="$1"; shift; target="$1";
shift; case "${dir}" in /*) this="${dir}/"; real="${dir}" ;; .)
this=""; real="/usr/src/tools" ;; *) this="${dir}/";
real="/usr/src/tools/${dir}" ;; esac; show=${this:-.}; echo "${target}
===> ${show%/}${1:+ (with: $@)}"; cd "${real}" &&
/usr/src/../tools/arm6/bin/nbmake _THISDIR_="${this}" "$@" ${target};
}; _makedirtarget makestrs dependall
*** Error code 2

Stop.
