If CONFIG_E500 is enabled, the compilation flags are updated specifying the target core -mcpu=e5500/e500mc/8540 Also remove -Wa,-me500, being incompatible with -mcpu=e5500/e6500 The assembler option is redundant if the -mcpu= flag is set. The patch fixes the kernel compilation problem for e5500/e6500 when using gcc option -mcpu=e5500/e6500.
