libffi/src/m68k lacks support for non-fpu m68k's.

Trying to build libffi standalone for m68k-rtems (a variant of m68k-elf) with a
modified libffi/configure.in:

# m68k-rtems4.7-gcc -m68000 -I.
-I/usr/local/src/packages/gcc/subversions/gcc/libffi/include -Iinclude

FYI: m68k-rtems is supposed to support these multilib variants:
# m68k-rtems4.7-gcc --print-multi-lib
.;

m5200;@m5200
