glibc 2.20 is now warning when _BSD_SOURCE is used (as it's replaced
by _DEFAULT_SOURCE), and czmq has the bad idea of forcing the usage of
-Werror, causing build issues with the recent NIOS II toolchain based
on glibc 2.20.
This commit adds a patch to czmq to fix that. The patch has been
submitted upstream.
