Given you reported the bug only to the glibc side, does it mean you
would like the glibc behaviour to be changed, and the binutils one to be
kept unchanged? We definitely want ldconfig to interpret paths relative
to the "chroot" directory (-r option), this is important to initialize a
cache without having to first chroot into the directory.

The manpage is provided by the manpages package and not by glibc.
