The test is trying to verify that the stackaddr that pthread_getattr_np
returns is valid, i.e. the program can access the location pointed to
by stackaddr. In the general case, stackaddr will be the edge of
RLIMIT_STACK or just within, which is why it looks to me that it would
be incompatible with the way sparc context switches work.
