> The Linux ABI differs from the non-Linux one with varargs, so this causes the tests to fail.

I think this is incorrect. This is due to difference between linux-gnu and linux-musl.

`-march=hexagon` uses the default target triple (which typically has linux-gnu on a linux-gnu system) and changes the arch part of `hexagon`.
This is subtly different from `-mtriple=...` which sets all components of a target triple.

I think the better fix is to replace -march= with -mtriple=, instead of keeping both.
