We don't have any specific patches but we're building our packages using
qemu-user and not qemu-system which is why we aren't running into memory
constraints that quickly.
For what is worth, you should use the "virt" flavor when running qemu-m68k
instead of the Quadra 800 flavor as this way you have more memory available.
See this video by Laurent Vivier created the "virt" target for m68k:

Here is the latest build log btw:

OK. The only other project that comes to my mind where you run into memory
exhaustion issue with qemu-system is the GHC Haskell compiler. Building it
on qemu-user works fine there, too.

Were those Debian qemu-user builds ever attempted on a 32-bit host?
