m32r: restore _BLOCKABLE
Commit a7f8388e
accidentally removed it... Al explains:
"Sorry, reordering breakage. In the signals tree here I have
static inline void sig_set_blocked(struct sigset_t *set)
...
and it's used all over the place (including quite a few places where
we currently have sigprocmask(SIG_SETMASK, set, NULL), which is what
it's equivalent to). With that done, m32r doesn't use _BLOCKABLE
anywhere, so it got removed. And that chunk got picked when I'd been
reordering the queue to pull the arch-specific fixes in front.
Sorry."
