    sh: Conditionalize gUSA support. · 83662461

    This conditionalizes gUSA support. gUSA is not supported on
    SMP configurations, and it's not necessary there anyways due
    to having other atomicity options (ie, movli.l/movco.l).
    
    Anything implementing the LL/SC semantics (all SH-4A CPUs)
    can switch to userspace atomicity implementations without
    requiring gUSA. This is left default-enabled on all UP so
    that glibc doesn't break.
    
    Those that know what they are doing can disable this explicitly.
