This is a bit thin for a decent error description. What does AC_PROG_CC
do that is wrong for you? And why do you need TARGET_CC? Are you
really trying to compile a compiler package using a Canadian Cross or
similar? (I'd assume that if you were, you wouldn't be asking this
question.)
If the package you are trying to compile isn't itself a compiler, then
you have no need for TARGET-something. Maybe you just want to use
AC_PROG_CC and use
./configure --host=m6812-elf
to invoke cross-compilation mode and use a compiler named m6812-elf-gcc?

Automake sticks an
_AM_DEPENDENCIES(CC)
at the end of AC_PROG_CC, and needs this for its dependency tracking.

Isn't the tool prefix usually some alias plus a hyphen '-'?

You should also be able to stick the Automake option no-dependencies
into AM_INIT_AUTOMAKE to avoid the error.

Hope that helps.
