As part of the autotuning process. GCC internally groups i686 and x86_64
together when determining how to tune for --march=native, and I'm pretty
sure I've added some i686 hardware for AMD when I was adding autotuning
support for AMD CPUs. Its similar for aarch64 and armhf, there are armhf
targets internally that accept armv8.X-a targets, so there's no need to
limit armhf tuning to armv7.
