[RFC PATCH 11/17] powerpc/e500: Use the correct assembler flags for e500mc and e5500

The "-me500" assembler option is intended only for use on e500v1 or
e500v2 systems.  On modern binutils it will refuse to assemble standard
floating point opcodes, and it will translate "lwsync" into "sync".

This fixes the e500mc/e5500 kernel build on recent binutils.

For e500mc/e5500 with standard PowerPC floating point, the assembler
options "-me500mc" or "-me500mc64" should be used, although they are not
strictly necessary depending on which opcodes are in use.
