[uutils coreutils] cp -rfT src des --> cp: prefix not found

[samwhelp]

Description

Ubuntu	coreutils
Ubuntu 25.04 (Plucky Puffin)	GNU Coreutils
Ubuntu 25.10 (Questing Quokka) Beta	uutils coreutils

The result of cp -rfT executed in uutils coreutils is different from the result in GNU Coreutils.

When executing some scripts in a chroot environment, I used cp -rfT.
The chroot environment uses uutils coreutils, so the command aborts with the error cp: prefix not found.
