Commite7607f7d6d("ARM: 9443/1: Require linker to support KEEP within OVERLAY for DCE") accidentally broke the binutils version restriction that was added in commit0d437918fb("ARM: 9414/1: Fix build issue with LD_DEAD_CODE_DATA_ELIMINATION"), reintroducing the segmentation fault addressed by that workaround. Restore the binutils version dependency by using CONFIG_LD_CAN_USE_KEEP_IN_OVERLAY as an additional condition to ensure that CONFIG_HAVE_LD_DEAD_CODE_DATA_ELIMINATION is only enabled with binutils >= 2.36 and ld.lld >= 21.0.0.
