- 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.
