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
