This breaks qtest_get_arch(), which attempts to parse the target architecture from the QTEST_QEMU_BINARY environment variable. Print an error instead of returning the architecture "kvm". Things fail in weird ways when the architecture string is bogus. Arguably qtests should always be run in a build directory instead of against an installed QEMU. In any case, printing a clear error when this happens is helpful.
