Not exactly. I tried to go down this route with the attached patch,
and it indeed fixes all the "Using '[…] in statically linked
applications requires at runtime the shared libraries from the glibc
version used for linking" warnings.

But copying zsh-static on a system with a different libc6 version
still segfaults, so this patch might be necessary but not sufficient.

Last line is:

  zsh-static: dl-call-libc-early-init.c:37: _dl_call_libc_early_init: Assertion `sym != NULL' failed.

So the attached patch is at least INCOMPLETE and only thought as base
for further debugging, not (yet) for inclusion in git.

Full strace of a run of zsh-static compiled with the attached patch on
Debian Unstable (glibc 2.32) and run on Debian 11 Bullseye (glibc
2.31) attached, too.
