[Buildroot] [PATCH v2 2/3] pru-software-support: add library for PRU firmware

TI provides a set of headers files and libraries useful in developing
firmware for real-time (PRU) cores embedded in some processors e.g.
AM3358.  This package stages these files for any packages creating
PRU firmware.

Note: As per [1], use commit v4.0.2 to sync with common TI Linux
      versions.
