Err, why would you need to rebuild glibc each time? Don't you know
exactly the dh_install command which fails?
Also, you don't need to try all combinations first: it's probably a bug
in just one package, so you just need to try to downgrade the various
packages by just one version. That makes just: downgrade libc, reboot,
try to run dh_install, downgrade hurd, reboot, try to run dh_install,
downgrade gnumach, reboot, try to run dh_install, and repeat up to
reaching the versions with which you believe it worked in the patch.
That should not take very long.
