I don't know whether this may be useful: if you generated make.sys via
the new "configure" script, $TOPDIR is set to `pwd` by default -- that
is, the directory you run configure from. However you can specify a
different directory by running:

  ./configure TOPDIR=/whatever/you/want

In all cases however $TOPDIR is presently hardcoded into make.sys as an
absolute path: thus, the same make.sys can't work for multiple build
trees without editing.

Using a relative path for $TOPDIR looks rather tricky, because make.sys
is included both by the top-level Makefile, and by the Makefiles of the
subdirectories: for this reason `pwd` isn't going to work either, and I
don't know of a command that computes "the directory this file is in".
Thus, right now, I can't see how that could be done. If you can, I'm
open for suggestions.
