Details
A common problem for people running remote tests (like mochitest-remote) on their local device is an incorrect MOZ_HOST_BIN. Often, this is mistakenly set to point to the Android build, rather than the desktop build. The resulting error does not explicitly identify the problem, prolonging developer pain. I would like to see something like "ERROR: unable to execute xpcshell on local computer; is your MOZ_HOST_BIN set correctly?" I am not sure how to detect this.

one thought is runtestsremote.py could sanity check the stdout/stderr from trying to launch the binary on the system. If it matches a known pattern we could determine that we do not have a proper binary or environment to run the application. In this case we can suggest via a nice error message that: "We are unable to run '<path>/xpcshell', please ensure that you can run this binary and that it is built for your local host computer"
