That's either a 2.6.39 bug or my m68k config needs to change for 2.6.39.

That should never have gone upstream into Linus's tree, uClinux is a
distro that focuses on nommu system development. (M68000 processors are
obsolete, so most of the action these days is around a derivative called
"coldfire" that started life as a nommu system and is still mostly used
So yeah, kernel bug. But we need to fix it.
If you can fix it to make it build, make a "-p1" style patch (like git
diff generates, if you have to create 'em yourself diff the "linux"
directories between a vanilla version and your modified version). Put
the patch in the "sources/patches" directory with a "linux-*.patch"
style name, and then re-run the build. It should pick it up automatically.
The FAQ has a long, drawn out explanation of the package cache if you
care. It makes building lots of targets faster, doesn't do so much for
building just one target:
