"build-tools". If we do not do this, the "depend" stage of
"buildworld" will build ``.depend'' and it will record the wrong
library and header dependencies (DESTDIR=${WORLDTMP}). Even worse,
the "all" stage may clobber build-architecture-format build tools
built in the "build-tools" stage with target-architecture-format ones.
