Start with the media-libs/libde265-1.0.16 src_install path shown in the log, focusing on the rm "${ED}"/usr/bin/acceleration_speed command and its multilib call chain. Reproduce the failure with the listed emerge command and inspect the complete build log. Done means the package emerges successfully without the install-phase error.
