    Pass -B to objcopy binary symbol test
    
    objcopy -I binary -O some_coff_target does not currently work without
    choosing a valid arch with -B.  This used to be the case for ELF
    targets too, until commit 6765ee1825d9.
    
            * testsuite/binutils-all/objcopy.exp (binary_symbol): Pass
            -B arch to objcopy.  Choose different output object files for
            the two tests.
