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

+        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.
