  269. During the build, many -I include directives are given with an
  270. absolute path. These absolute paths end up in the hashes that
  271. are computed by ccache. Therefore, when you build from a
  272. different directory, the hash will be different and the cached
  273. object will not be used.
  274. To improve cache performance, set this option to y. This
  275. allows ccache to rewrite absolute paths within the output
  276. directory into relative paths. Note that only paths within the
  277. output directory will be rewritten; therefore, if you change
  278. BR2_HOST_DIR to point outside the output directory and
  279. subsequently move it to a different location, this will lead
  280. to cache misses.
