powerpc/e500: Set -mcpu flag for 32-bit e500
Unlike 64-bit, we don't currently support multiplatform between e500 and non-e500, so the -mcpu is not configurable at this time. -msoft-float is specified when testing for -mcpu=8540 because otherwise some older toolchains will fail with "error: E500 and FPRs not supported".
