Doing the 1st alternative gives a default which is usually the right
thing
to do for an embedded target.  Let all tic4x configurations that don't 
specify any OS use coff.

In this case, using the 1st alternative should help make the tic4x-rtems
and
tic4x-coff targets fall into the same case.

That is a habit from targets that include version information at the end
of the OE part.  Sometimes you see targets like sparc-solaris2.7 so 
using sparc*-*-solaris* covers the variants users can enter.
