WARNING:
rtems/gcc (implicitely) uses -maltivec on all 74xx CPUS and the MVME5500 calls for -mcpu=7450.
Unfortunately, with -maltivec, gcc uses vector registers for some optimizations.
--> until proper altivec support is implemented in RTEMS random *data corruption* must be expected.
Workaround:
make/custom/mvme5500: use -mcpu=750
--> Until we know what we do for altivec, it might be a good idea to alias 74xx to 750 in the gcc/newlib multilib configuration...
