    x86emul/test: correct compiler checking and avoid it when merely cleaning
    
    The error messages that the compiler may emit can be confusing.
    
    The check was also the wrong way round in case multiple make targets are
    specified: We want to do the check whenever targets other than the running
    and cleaning ones are specified.
    
    Fixes: 05f4cc219235 ("x86emul: suppress default test harness build with 
incapable compiler")
    Fixes: d5997399b7ad ("x86emul: suppress "not built" warning for test 
harness'es run targets")
