[sugar] Error building squeak in jhbuild on Ubuntu 8.10

[Morgan Collett]

When building jhbuild on Ubuntu 8.10, I get the following error building squeak:

/bin/bash /home/morgan/sugar-jhbuild/source/squeak/bld/libtool

This has also been reported by the developer packaging squeak for Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/squeak-vm/+bug/254547

That bug report suggests building with -D_FORTIFY_SOURCE=0 - or is
there a better way of fixing this?
