	  Arm toolchain for the ARM architecture. It uses GCC 10.3,
	  GDB 10.2, glibc 2.33, Binutils 2.36.1. It generates code
	  that runs on all Cortex-A profile devices. The code
	  generated uses the hard floating point calling convention,
	  and uses the NEON FPU instructions.

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