Right. We are missing a distro-wide location for this information. Currently it is effectively defined by the default build settings of gcc. But really we should have an agreed place to find this info and all compilers (but not jits as they can just use 'this machine I'm on') should use the same defaults. I'm not sure how many compilers we use to pre-build things in the archive but I suspect there are quite a few. I filed a bug aginst llvm recently as it doesn't even have a mechanism to set this info, for distros to use, yet. Deciding to have such info writen down somewhere is a good start, but ther remains an interesting question about what format you write it down in, as presumably each compiler uses (slightly?) different ISA terminology. I'd certainly like to follow up this problem next year. A useful start would be if people could list the affected packages, beyond gcc* and llvm-toolchain*.
