	  Arm toolchain for the ARM architecture. It uses GCC 9.2.1,
	  GDB 8.3.0, glibc 2.30, Binutils 2.33.1. It generates code that
	  runs on all Cortex-A profile devices, but tuned for the
	  Cortex-A9. The code generated uses the hard floating point
	  calling convention, and uses the VFPv3-D16 FPU instructions.

	  This is the same toolchain that was previously distributed by
	  Linaro.
