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.

          This can reduce on disk and in-memory size of the kernel
          code and static data, particularly for small configs and
