ldconfig missing in glibc-2.3.5
so glibc-2.3.5 from experimental builds fine on Debian GNU/Hurd if one
adds --without-tls (see #309489). However, binary-arch fails as the
ldconfig patch got disabled by gotom, while the build system still tries
to install it and fails.
As I am not sure whether Jeff still got time for that, somebody else
should perhaps have a look at the old patch (still in the Debian source
package, but not in debian/patches/00list) and see how to enable it
