The way I understand it, they only want to skip or xfail some tests for
older glibc, not for !glibc, so I think the logic is what they wanted.

I don't follow the reasoning (why do you say that AVX dispatch requires
glibc?) and I'm not convinced the _glibc_older_than part is correct,
but the diff does improve things on arm64 as well:

current:

= 99 failed, 46311 passed, 347 skipped, 3634 deselected, 32 xfailed, 2 xpassed, 76 warnings in 355.65s (0:05:55) =

with your diff below and the catan diff applied to libm:

= 87 failed, 46330 passed, 336 skipped, 3634 deselected, 36 xfailed, 2 xpassed, 75 warnings in 283.99s (0:04:43) =
