GDB can read DWARF 2 binaries just fine.  However, DWARF 2 isn't as
standardized as you might think; different compilers tend to have
different views of what the standard says in some respects.  So, how
well it will work is a bit of an open question.

Probably not.  The Application Binary Interface for ColdFire just isn't
that well-defined, or uniformly implemented.  It *might* work, but
you're likely to run into some problems.
