+       bool

+         Select this if the architecture wants to use thin archives
+         instead of ld -r to create the built-in.o files.

+config LD_DEAD_CODE_DATA_ELIMINATION
+       bool
+       help
+         Select this if the architecture wants to do dead code and
+         data elimination with the linker by compiling with
+         -ffunction-sections -fdata-sections and linking with
+         --gc-sections.
+
+         This requires that the arch annotates or otherwise protects
+         its external entry points from being discarded. Linker scripts
+         must also merge .text.*, .data.*, and .bss.* correctly into
+         output sections. Care must be taken not to pull in unrelated
+         sections (e.g., '.text.init'). Typically '.' in section names
+         is used to distinguish them from label names / C identifiers.
