m68k_swap_u* broken for mcf5203elite/m5200

[Ralf Corsepius]

Building the mcf5203elite breaks errors like this:

{standard input}:3664: Error: invalid instruction for this architecture; needs 68000 or higher -- statement `rorw #8,%d1' ignored

Examiniating the asm-code seems to indicate the "rorw" instructions being unconditionally applied by the m68k_swap_* macros from exec/score/m68k.h not to be supported by m68k-rtems-as -m5200.

Release:
RTEMS-CVS 20020308

How-To-Repeat:
With rtems-cvs/shapshots including dosfs:
../rtems/configure --target=m68k-rtems
make RTEMS_BSP=mcf5203elite
