It seems that lddtree is used to detect broken binaries which is part of pax-utils.
This is not documented anywhere (nor any other software required) by the look
of it so I had to look at the initramfs generation script to find out what's going
on as well as make a search what software provides lddtree.
I guess using ldd should be fine and reduce the dependencies needed. I don't
know if pax-utils is part of "system" (or whatever the meta word for base is on
Gentoo) but installing pax-utils just for generating initramfs on distribution other
than Gentoo doesn't seem right to me.
