Optional toolchain targets (Used upon request)

The following targets should not be called in the typical development. They should be called by CI and only upon request, i.e., NOT be built regularly.

Target	Description
toolchain	Build GCC toolchain for the security core/SMC
toolchain_llvm	Build LLVM toolchain for the vector core
toolchain_vp	(Optional) Build GCC toolchain for the vector core
