Connecting to a /dev/nbdN device is a Linux-specific action. We were already masking -c and -d from 'qemu-nbd --help' on non-linux. However, while -d fails with a sensible error message, it took hunting through a couple of files to prove that. What's more, the code for -c doesn't fail until after it has created a pthread and tried to open a device - possibly even printing an error message with %m on a non-Linux platform in spite of the comment that %m is glibc-specific. Make the failure happen sooner, then get rid of stubs that are no longer needed because of the early exits. While at it: tweak the blank newlines in --help output to be consistent, whether or not built on Linux.
