Hi,

I've tried to patch the glibc package for the problems noted at
<https://lists.gnu.org/archive/html/bug-hurd/2021-08/msg00007.html>;.

I've found two recent patches (glibc-hurd-proc-reauth.patch and
glibc-hurd-sendmsg-SCM_CREDS.patch) that appeared relevant.  I tried
to patch our glibc package with those patches.

The modified tarball builds fine for --system=x86_64-linux, but not
for --system=i586-gnu (tested with ./pre-inst-env guix build hello
--system=i586-gnu).  Any idea what's happening here?

Greetings,
Maxime.
