Given that gcc-4.0 -O3 also generate wrong code on i386, there is no
need for a m68k specific hack. Every package that use -O3 will have to
be rebuild on all plateform anyway when gcc has stabilized. On m68k, gcc
is just nice enough to do an ICE instead of random code generation.
Imagine a large red swirl here.
