And also:

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

/usr/lib/x86_64-linux-gnu/libgcc_s.so.1
root@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.
