From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>
The identify_qemu_vcpus bash function can return numbers including
whitespace characters, which can be a bit annoying in some bash
dollar-sign substitutions. This commit therefore strips all spaces and
tabs from the value that identify_qemu_vcpus outputs.
