    testsuite, Darwin: Remove an unnecessary flags addition.
    
    The addition of the multiply_defined suppress flag has been handled for some
    considerable time now in the Darwin specs; remove it from the testsuite libs.
    Avoid duplicates in the specs.
    
    Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
    
    gcc/ChangeLog:
    
            * config/darwin.h: Avoid duplicate multiply_defined specs on
            earlier Darwin versions with shared libgcc.
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/lib/libstdc++.exp: Remove additional flag handled
            by Darwin specs.
    
    gcc/testsuite/ChangeLog:
    
            * lib/g++.exp: Remove additional flag handled by Darwin specs.
            * lib/obj-c++.exp: Likewise.
    
    (cherry picked from commit 3c776fdf1a825818ad7248d442e846f532574ff7)
