Fixed by making pthread_getattr_np output consistent before and after an
execstack DSO is loaded. The split vma (or even a non-executable portion after
the first frame) does not really make any operational difference and we'd like
to keep as less of the stack as executable as we can get away with in the
interest of security paranoia.
