And also:

    root at kvm-10487:~# dpkg -l | grep -Fe linux-image-5.2.0-2-amd64 -e libc6 -e libgcc1

    root at kvm-10487:~# readlink -e /lib/x86_64-linux-gnu/libc.so.6 /lib/x86_64-linux-gnu/libgcc_s.so.1
    /usr/lib/x86_64-linux-gnu/libc-2.29.so
    /usr/lib/x86_64-linux-gnu/libgcc_s.so.1
    root at kvm-10487:~# cat /etc/ld.so.conf.d/x86_64-linux-gnu.conf 
    # Multiarch support
    /usr/local/lib/x86_64-linux-gnu
    /lib/x86_64-linux-gnu
    /usr/lib/x86_64-linux-gnu

So AFAICT libc6 installs its soname under /lib/$MULTIARCH, and with the
default ld.so.conf ldd(1) looks there before its counterpart in /usr, so
that's what we want LIBC_DIR to be.
