toolchain-external: add Arm ARM toolchain 8.2-2018.08

This is the same toolchain that was previously distributed by Linaro. [1]

Switch default toolchain as this toolchain supersed the Linaro ARM toolchain.
Only x86_64 host are supported, so keep Linaro toolchain for x86 host.

Tested with qemu_arm_vexpress_defconfig.

+         Arm toolchain for the ARM architecture. It uses GCC 8.2.1,
+         GDB 8.1.1, glibc 2.28, Binutils 2.30. 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.
