Enable DSPr2 SIMD extensions if CPU type is mipsel

The DSPr2 extensions have been verified to work with little endian MIPS.
Whether or not CMAKE_SYSTEM_PROCESSOR is set to "mips" or "mipsel" in a
little endian MIPS environment seems to be inconsistent, but our build
system needs to handle both cases.
