Ian Lance Taylor b95cd48b01 libgo: remove old MIPS architecture names
This removes the old names for the 3 main MIPS ABIs: mipso32, mipsn32
    and mipsn64. It also removes the mipso64 ABI which has no equivalent
    architecture name in go. This ABI has been dead for sometime and I doubt
    anyone will miss it.
