These often lag years behind the recent > gcc releases :( In those scenarios, why do you need to build mainline? Aren't your customers using longterm or frozen kernels? If they are paying for certified GCC images, aren't they already paying for supported kernel images from some vendor too? I understand where you are coming from -- I have also dealt with projects/machines running ancient, unsupported software/toolchains for various reasons; but nobody expected upstream (and in particular the mainline kernel source) to support them. In the cases I experienced, those use cases require not touching anything at all, and when the time came of doing so, everything would be updated at once, re-certified/validated as needed and frozen again.
