commit r12-7489-gc18ddb05b0391a397f8882fc6a12a1bab7e0df52

    Darwin, libgcc: Fix build errors on powerpc-darwin8.
    
    PowerPC Darwin8 is the last version to use an unwind frame fallback routine.
    This had been omitted from the new shared EH library, along with one more
    header dependency that only fires there.
    
    Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
    
    libgcc/ChangeLog:
    
            * config/rs6000/t-darwin-ehs: Add darwin-fallback.o.
            * config/t-darwin-ehs: Add dependency on unwind.h.
