[Buildroot] [PATCH v2 1/6] package/binutils-bare-metal: new package

This patch adds a new package for building binutils for a bare-metal toolchain.
The cpu architecture is defined by a toolchain-bare-metal virtual package.
While any cpu architecture could be used, the default configuration will be a
Xilinx microblaze little endian architecture, so that buildroot will be able
to build the microblaze firmware applications for zynqmp and versal.
When configured for the Xilinx microblaze architecture, all of the binutils
patches that are applied to the Xilinx distributed toolchain will be applied
in order to generate a toolchain that is equivalent to what Xilinx distributes.
