No, not without modification.  Note that this is not a trival thing
to do.  GNAT can be built as a cross compiler, and I actually did
this for VxWorks targets, but you really have to know what your
are doing.

You first need to build the GCC cross compiler for x86/Coldfire,
and this includes binutils and newlib (for the same target).
You can start by trying to modify the crossm68k port to be
crossx86.

If you get that far, then you'll have to target GNAT for the
same target (by default, if GNAT doesn't recognize the
configure target, you'll get a GNAT with no run-time, so
even the Ada delay statement will not work).  Then you'll
have to figure out how to add basic run-time support.
