Bug#759870: gcc-4.9: Compiles zsh endlessly on s390x (maybe sigjmp_buf related)

[Matthias Klose <doko@debian.org>]

Control: severity -1 important
Control: tags -1 + help

if it's just zsh, then it's not serious.  Apparently there are some stability
issues with some s390 machines, as seen with other builds as well. CC'ing the
s390 porters.
