Attached is a patch against git master that works for me:
,----
| % lsinitramfs /boot/initrd.img-$(uname -r) | grep libc.so.6
| lib/i386-linux-gnu/libc.so.6
`----

Subject: [PATCH] copy_exec: Handle optimized libraries under multiarch paths
In a multiarch world, libraries are not directly installed under
{/usr,}/lib, but one directory below. Adjust the search accordingly.
Closes: #636495
