   How hard do people think it would be to add an ld feature as follows?

   I have in mind a new option, perhaps `--remove-unneeded-sections', that
   would tell ld to discard from the output any input sections to which no
   relocs in other sections refer.  It could be positional and apply to some
   input files and not others, or it could just take the input section
   containing the entry point as the root of the section dependency graph. 

It's a great idea, and Richard Henderson has already implemented it
for most ELF targets.  It's called --gc-sections.
