The right test case to detect errors like this is spcontext01 which uses
two functions provided by the CPU port:
void _CPU_Context_volatile_clobber( uintptr_t pattern );
void _CPU_Context_validate( uintptr_t pattern );
Maybe
cpukit/score/cpu/microblaze/microblaze-context-validate.S
could be improved to check also the msr?
