Pretty old ... ;)

-m5200 a coldfire-cpu?

Seems to me, as if your m68k-*binutils and/or m68k-*gcc is/are too old 
to be able to build newlib-1.18.0. IIRC, gcc-3.3.6 didn't support the 
coldfire, but coldfire support was added to gcc some time during the 
gcc-4.x release series (Unfortunately, I don't recall the details).

You could try bootstrap'ing the whole toolchain with current binutils 
and gcc+newlib.
