        crypto: aes-generic - fix aes-generic regression on powerpc
    
        commit 6e36719fbe90213fbba9f50093fa2d4d69b0e93c upstream
    
        My last bugfix added -Os on the command line, which unfortunately
        caused  a build regression on powerpc in some configurations.
    
        I've done some more analysis of the original problem and found
        slightly different workaround that avoids this regression and also
        results in better performance on gcc-7.0: -fcode-hoisting is an
        optimization step that got added in gcc-7 and that for all gcc-7 versions causes
        worse performance.
    
        This disables -fcode-hoisting on all compilers that understand the
        option. For gcc-7.1 and 7.2 I found the same performance as my previous
        patch (using -Os), in gcc-7.0 it was even better. On gcc-8 I could see
        no change in performance from this patch. In theory, code hoisting
        should not be able make things better for the AES cipher, so leaving it
        disabled for gcc-8 only serves to simplify the Makefile
        change.
