Currently, they are individually listed as exclusions in the\ntoolchain choice.\n\nThis poses a maintainance burden, as the knowledge about what gcc\nversion supports what architecture is split across many places: the\ntoolchain choice, the gcc version choice, the external toolchains.\n\nAs a first step, add a blind option that architectures or individual\ncores may select to indicate they lack support in our internal backend.\n\nActual use of the option will come in followup patches.\n\nSigned-off-by: \"Yann E.
