libzmq is used by fbzmq, which absolutely requires libstdcpp since it's a
C++14 project. There's no point in using two libc++.
Cleaned up Makefile for consistency between packages.
Added nanosleep patch for platforms that are missing usleep.

Compilation for the zmq lib is broken for c++ stdlib in openwrt since the
patches add uclibc++ specific code.
This diffs changes the patch to only include the code conditioned
on if we are actually using uclibc++.
