I have only seen this error when using the latest uClibc from CVS.  If
you are using the uClibc.tar that is included with the m68k-elf-tools
you should not see this error.

Make sure you modify the build-uclinux-tools.sh to use the uClibc from
that tarball included with the tools.

I am just about done on a new script/tools release,  you might like to
hold off a day or so for that if you can,

Cheers,
