tinyconfig: enable CONFIG_LD_DEAD_CODE_DATA_ELIMINATION

This CONFIG option, if supported by the architecture, helps reduce the
size of vmlinux.

For example, the size of vmlinux with ARCH=arm tinyconfig decreases as
follows:

   text    data     bss     dec     hex filename
 631684  104500   18176  754360   b82b8 vmlinux.before
 455316   93404   15472  564192   89be0 vmlinux.after
