[Buildroot] [PATCH v2 1/3] package/arm-gnu-rm-toolchain: new package

[kostap at marvell.com]

From: Konstantin Porotchkin <kostap at marvell.com>

Add cross-compialtion ARM RM toolchain for supporting firmware
builds for Armv8-based SoCs utilizing Cortex-M/Cortex-R
service CPUs.
The cross-toolchain used for building Armv8 application CPU
code cannot be used for Cortex-M/Cortex-R 32-bit THUMB code
generation.
This patch installs pre-built bate metal ARM GNU-RM toolchain
into the host file system folder $(HOST_DIR)/opt/gcc-arm-none-eabi
for covering the above mentioned cases.
