This also affects building CURRENT from a 9.1 system. One workaround is
to build without -j, but this is quite painful on an 8-core box.

I tried using bmake from ports, but this fails, because the build system
seems to have PATH hardcoded and it doesn't include /usr/local/bin. With
`which bmake` -j8 buildworld it seems to work, though, but it is not
finished compiling yet.

Maybe a paragraph about the proper way to upgrade could be added to the
UPDATING entry?
