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.
