I was doing some review of rtld-audit changes we might want to backport, and
I just wanted to close the loop here that this is committed to the glibc
development branch as of November 21st and will be in glibc 2.37, and has
already been backported all the way to glibc 2.34 (which introduced the key
fixes for aarch64 in rtld-audit).

We could have written a test case for this, but it's an odd testcase
because it's about ensuring we touch minimal register state as we return
through the pltexit case.

Sending this email mostly for my own records so I remember what we did.
