I just tried this, and it appeared to work fine.  A transcript of the build
is appended.  I've placed a copy of the resulting executable in

	[...]/unix/2.0/bin/SqueakVM-2.0h-i586-linux-2.0.29

on alix.inria.fr (sorry about the stale version of Linux -- my portable is
not switched on at present, and the Linux boxes at work are still in the
dark ages ;^).
