I've tried to patch the glibc package for the problems noted at
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?
