*Enable RISC-V global pointer relative addressing*

Type: ``bool``

Help
====

.. code-block:: none

    Use global pointer relative addressing for small globals declared
    anywhere in the executable. It can benefit performance and reduce
    the code size.

    Note: To support this feature, RISC-V SoC needs to initialize
    global pointer at program start or earlier than any instruction
    using GP relative addressing.
