Capturing some additional notes regarding the purpose of multiarch platform triplets. These triplets should unambiguously capture:
* syscall ABI (~= kernel)
* instruction set (IA-32, IA-64, PowerPC, ARM, ARM64, etc)
* endianness (big- or little-
* word size (32- or 64-)
The initial set of triplets from Debian covers GNU/Linux, GNU/Hurd and GNU/FreeBSD. Issue 23969 covers accurately capturing Mac OS X details, while issue 23670 covers iOS. (Issue 23496 should also likely take the issue 22980 changes into account for the Android cross-build)
I've added Steve Dower to the nosy list as it would also be good to have a set of triplets defined for Windows. MAL suggested in issue 22980 that it may be worth capturing this ABI compatibility identification discussion as a PEP rather than solely as a set of issues with resulting changes to the documentation, which I think is a reasonable direction to go (even if it's done primarily as an after-the-fact communication of the build identification changes for inclusion in What's New, rather than a gating requirement for actually doing the work).
