[kaffe] compiling for m68k with optimization works.

[Kiyo Inaba]

Tentative conclusion for m68k-linux with -O.

After applying several mods including 'ifaddrs_linux.c' and 'ssize_t'
issue, I can compile kaffe-030425 with or without -O.
But, if I compile
1) kaffe/kaffe/main.c
2) libraries/native/Class.c
with -O flag, the generated kaffe-bin does not work. If I configure
everything with -O flag, and make, and finally compile these two
files without -O flags, the generate kaffe-bin can (at least) compile
'HelloWorld'.

Interesting, and don't know more detailed reason for this...
