Are you linking with the correct libc ? If you have the LC part you do 
not have an FPU. If your linker command or tools are not correct the 
default 68020 library links and that requires a FPU. This always trips 
in the printf function first.

A simple check is:

  m68k-rtems4.11-objdump -d myapp | grep fmovemx
