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\nYes, the logic is inverted, because the very large majority of archs and\ncores do have support in upstream gcc (or in a vendor fork we support,\nlike bfin and arc). Only a very few do not, and it is much easier to\ncater to those rather than all the others.\n\nActual use of the option will come in followup patches.\n\nSigned-off-by: \"Yann E.
