In 
https://salsa.debian.org/glibc-team/glibc/-/commit/5e3aa111654e9aad080881fb98f9e5b01b277857
(currently only available via Debian experimental),
the duplicated paths for /lib were removed from ld.so.conf files.

This triggered a build failure for ncl, hdf-eos5 and ruby-hdfeos5.

All those packages link against libgctp and the build failures look
similar:

If you want to reproduce the problem, remove the line
/lib/x86_64-linux-gnu
in /etc/ld.so.conf.d/x86_64-linux-gnu.conf and try to build one of those
packages in debian sid or trixie.

The problem can be reproduced in Debian sid, with no ld.so.conf
modifications. (Or I botched my testing?)

I can't repoduce the failure with with no ld.so.conf modifications.
