I already told you what I can provide.

I'm not sure I fully understand the issue here:

See, glibc used to work for alpha up until 2.33 as I read. Then a change
broke it for alpha with 2.34. Does the respective glibc maintainer for
alpha (Richard Henderson according to [1]) really have no interest in
fixing it?
