This is expected since you built a cross-compiler for m68k, but not a
libc for m68k that you can link with.

Blindly removing the -lc option is *not* what you wanted to do.

Ah, no.  This is just another issue in a long list of issues that
you're going to run into since you really don't have a clear
understanding of the linux environment, or how to build cross-target
toolchains. 

Again, go look at:

http://www.uclinux.org/

where you'll find kernels that have been modified to support m68000,
as well as toolcahins that can build that kernel as well as the
userland applications you want to run.

Until you have a much clearer understanding of what you are trying to
do, blindly throwing together a cross-compiler is not going to get you
there.
