kbuild: reword help of LD_DEAD_CODE_DATA_ELIMINATION
Since commit 5d20ee3192
("kbuild: Allow LD_DEAD_CODE_DATA_ELIMINATION
to be selectable if enabled"), HAVE_LD_DEAD_CODE_DATA_ELIMINATION is
supposed to be selected by architectures that are capable of this
functionality. LD_DEAD_CODE_DATA_ELIMINATION is now users' selection.
Update the help message.
