libc actually queries processor for current OSXSAVE and supported XSAVE bits. Maybe it is possible to provide standalone binary replicating these tests.
So basically you're saying the /lib64/ld-linux* --help test is the authoritative one, and both inxi and "that other script" can't actually be correct anyway, is that right?
Not sure if this detail is really relevant - if the CPU supports
saving the AVX state then our kernels will have that enabled. In theory
you can probably run a virtual machine with the AVX state saving
disabled but does that really matter here? That is, we don't support
running a very old kernel without AVX support with ALP.
