Did you run buildworld and installworld on different versions (e.g: main
vs.  stable, or main vs. main pre e7a629c851d7)? This is is the only way
I can reproduce this.

main built on stable/14:

$ ldd
/usr/obj/tmp/home/herbert/source/freebsd/head/src/amd64.amd64/tmp/legacy/bin/sort
/usr/obj/tmp/home/herbert/source/freebsd/head/src/amd64.amd64/tmp/legacy/bin/sort:
        libmd.so.6 => /lib/libmd.so.6 (0x311068a44000)
        libc.so.7 => /lib/libc.so.7 (0x311068df0000)
        [vdso] (0x3110676f0000)

main built on main:

$ ldd
/usr/obj/home/herbert/source/freebsd/head/src/amd64.amd64/tmp/legacy/bin/sort
/usr/obj/home/herbert/source/freebsd/head/src/amd64.amd64/tmp/legacy/bin/sort:
        libmd.so.7 => not found (0)
        libc.so.7 => /lib/libc.so.7 (0x28eb0e6f000)
        [vdso] (0x28eafac0000)

I think these files (sort, mtree, etc.) are copied from /usr/[s]bin.
