    rts: Don't build StgCRunAsm.S if unregisterised
    
    StgCRunAsm.S provides StgCRun on powerpc64le platforms when
    registerised.  However, in the unregisterised setting we use the
    mini-interpreter and consequently shouldn't build StgCRunAsm.S lest we
    get duplicate symbols.
    
    Test Plan: Build unregisterised compiler on AIX.
