I wanted to drop it to make sure that I didn't miss any references to it
(and that we didn't add any in the future). But -Wunused also complains
if you leave it in. :)

I think we can reorganize the code a little to make the end result more
readable. Like this.

  [1/2]: system_path: move RUNTIME_PREFIX to a sub-function
  [2/2]: git_extract_argv0_path: do nothing without RUNTIME_PREFIX
