Invoking runqemu outside of the build directory for an
in-tree setup results in an empty TMPDIR because bitbake -e
cannot be run to find it.
A symptom of this problem is running runqemu and getting the
following error:
Error: Unable to find tunctl binary in <directory>
Catch this case and report the error to the user.
This fixes [YOCTO #1278]
