Use OEMASK to mask out glibc-3.4 and glibc-initial-3.4. Then OE will use gcc 3.3.x and this will be compatible with oz 3.3.6-pre1.
(The more sane option is, of course, to help us make OE build OZ images... many things will be much better when we are at that point, e.g. no more hacking on unmaintained outdated images like 3.3.x)
