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.

Changes v1 --> v2
 * extract source to $(@D) cleanly (suggested by Thomas)
 * be more explicit about licensing (suggested by Arnout)
 * switch to buildroot-suitable name: PRU_CGT --> TI_CGT_PRU_DIR
 * sundry clarifications

Changes v2 --> v3
 * avoid re-use TI_CGT_PRU_DIR --> TI_CGT_PRU_INSTALLDIR
 * don't install to a version-specific path
 * typo fixes
 (all suggested courtesy of Arnout)
