Fixes for m68k

2004-03-15  Dalibor Topic <robilad at kaffe.org>

        * config/m68k/clear-cache.h:
        Removed.

        * config/m68k/jit.h:
        Reverted patch since it breaks things on non-linux platforms.

        Reported by: Tony Wyatt <wyattaw at optushome.com.au>

        * config/m68k/linux/jit-md.h:
        Added linux specific cache clearing code.

        *  config/m68k/linux/clear-cache.h:
        New file. Fixed #define.

        Reported by: Riccardo Mottola <zuse at libero.it>
