arch: add option to disable internal toolchain backend
Some architectures or specific cores do not have support in upstream
gcc. Currently, they are individually listed as exclusions in the
toolchain choice.
This poses a maintainance burden, as the knowledge about what gcc
version supports what architecture is split across many places: the
toolchain choice, the gcc version choice, the external toolchains.
As a first step, add a blind option that architectures or individual
cores may select to indicate they lack support in our internal backend.
Actual use of the option will come in followup patches.
