Maybe follow the entries for other architectures, for instance following
riscv32 and arc:

  * Support for OpenRISC running on Linux has been added.  This port requires
    as least binutils 2.35, GCC 11, and Linux 5.4.  Currently only soft-float
    ABI is supported.

    (maybe also add the triple name here).
