This allows building with toolchains that by default target e6500.
When targetting e6500, GCC generates a two-operand form of mfcr which gas normally maps to mfocr. However, when we tell gas to target e500 rather than e6500, it rejects two-operand mfcr. Tell GCC to target a least-common-denominator e500 to match what we tell the assembler.
