For\nexample, ARM's cortex-a35 requires gcc-5, while cortex-a73 requires\ngcc-7. Same goes for other architectures, of course.\n\nCurrently, we hard-code every such conditions in the gcc version choice,\nas well as in the individual external toolchains.\n\nHowever, as we add even more CPU variants, the conditions are getting\nmore and more complex to write and maintain.\n\nIntroduce new symbols, that architectures can select if they have a\nspecific requirement on the gcc version. gcc and external toolchains\ncan then properly depend on those symbols.\n\nThe burden of maintaining the requirements on the gcc version now falls\ndown to the architeture, instead of being split up in gcc and all the\nexternal toolchains.\n\nAs the oldest gcc version to handle, we can either choose gcc-4.9, as\nthe odlest version we support in our internal toolchain, or choose\ngcc-4.8, as the oldest external toolchain we support (except for the\ncustom ones, but they'll be handled specifically in upcoming changes).\nWe choose to go back up to gcc-4.8.\n\nSigned-off-by: \"Yann E.
