[PATCH] powerpc: Update compilation flags with core specific options

From: Catalin Udma <redacted>

If CONFIG_E500 is enabled, the compilation flags are updated
specifying the target core -mcpu=3De5500/e500mc/8540
Also remove -Wa,-me500, being incompatible with -mcpu=3De5500/e6500
The assembler option is redundant if the -mcpu=3D flag is set.
The patch fixes the kernel compilation problem for e5500/e6500
when using gcc option -mcpu=3De5500/e6500.
