When building with CONFIG_LD_DEAD_CODE_DATA_ELIMINATION,
-fdata-sections and -ffunction-sections are being enabled by the
top-level Makefile, and module section merging is also needed.
Expand the ifdef (and the comment block) to cover that case too.
Fixes: 6a3193cdd5e5 ("kbuild: lto: Merge module sections if and only if
CONFIG_LTO_CLANG is enabled")
