[Buildroot] [PATCH 1/2] ti-cgt-pru: add package for PRU Host toolchain

TI provides a binary code generation toolchain to develop firmware for
the programmable real-time unit/co-processor found in some SOCs such as
some models in the AM335x line. This toolchain includes C/C++ support
(clpru) rather than just assembler (pasm) supported by the pre-existing
am335x-pru-package [1]. Following the lead of the Yocto meta-ti
layer [2], this package provides a host toolchain suitable for an x86
(or x86_64) Linux targeting an ARM-based PRU core.
