Useful on ARM, especially on TI and other platforms with GPIO (eg, beaglebone, raspberrypi). Seems to be required by TI SGX/PowerVR graphics and related tools.
This is just the upstream code with some cleanups and a simple Makefile for Gentoo and OpenEmbedded. To compile by hand, just set CC and CFLAGS on the make command-line.
