kbuild: reword help of LD_DEAD_CODE_DATA_ELIMINATION
Since commit 5d20ee3192a5 ("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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
