OK, so digging into this a bit further, I noticed glibc actually got
updated a long way in my last upgrade. It went from glibc-2.33.9000-
2.fc35.x86_64 to glibc-2.33.9000-23.fc35.x86_64 . It seems a lot of the
intermediate builds were done in side tags and not tagged, and rawhide
only went from -2 to -18 in 20210617.n.0; the last time I updated my
system before yesterday was on the 16th.

Kevin checked and saw he also had -2 until he updated, and when he
tried downgrading, he didn't go back that far. So, I suspect glibc is
the culprit here. I did try downgrading all the way back to -2 to
verify, but it more or less bricked my system; I could try again but I
think I'd have to downgrade virtually everything that got upgraded in
the transaction to avoid bricking, which wouldn't prove much.

I'm just gonna go ahead and file a glibc bug and we'll see if we can
figure it out there. For now I'm using current packages with the
MESA_LOADER_DRIVER_OVERRIDE workaround.
