Sigh, indeed 'new' kernel sigset_t has the same size as previous one,
it has changed only to use a struct. I still think it would be feasible
to change uc_sigmask to glibc sigset_t, the *context functions is
already using the expected sizes for __NR_sigprocmask. Do you see 
anything that need further adjustment?
