glibc regression on alpha with 2.34+

Hello!

I just noticed that there is a regression in glibc on alpha with version 2.34 or later.

Looking at the build logs for Debian's 2.34-8 [1], 2.35-4 [2] and 2.36-4 [3], it's obvious
there is something wrong given the many "Segmentation Fault" errors.

I had hoped I could fix this issue by passing "--disable-default-pie" like we already did
on sparc64, but it seems it's not the same bug [4]. At least, this particular workaround
does not help.

I think the best approach would be bisecting this from 2.33 to 2.34 using the glibc sources
from git. I assume building glibc and running the testsuite should be enough for bisecting.
