toolchain/toolchain-bare-metal-buildroot: update help text for multiple tuple support

Browse Source 
Now that binutils-bare-metal, gcc-bare-metal and newlib-bare-metal packages
have been upgraded to support a list of architecture tuples, this patch
updates the toolchain-bare-metal-buildroot help text to describe the new
capability.

BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH is still backwards compatible with
its prior definition as defining a single tuple with this new definition
works exactly the same as before.

This option allows to define the architecture tuple for the
bare-metal toolchain.
This option allows to define the list of architecture
tuples for which bare-metal toolchains will be created.
One toolchain will be built for each of the architecture
tuples specified in this option.
For example, to build both a Microblaze and a RISC-V bare
metal toolchain, use the following definition:
"microblazeel-xilinx-elf riscv32-buldroot-elf"
source "package/newlib-bare-metal/Config.in"
