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.

One toolchain will be built for each of the architecture

For example, to build both a Microblaze and a RISC-V bare
