Commit Message

This patch adds a new package for building newlib 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.
