Solved, or at least workarounded: Not using -fstack-protector-strong
(but keeping -fstack-protector) on s390x solves the hanging gcc 4.9.
(gcc 4.8 doesn't even know this option.) Doesn't seem to affect other
architectures. Details are at https://bugs.debian.org/759870

Will adapt Debian's s390x builds of zsh accordingly.

		Kind regards, Axel
