  287. During the build, many -I include directives are given with an
  288. absolute path. These absolute paths end up in the hashes that
  289. are computed by ccache. Therefore, when you build from a
  290. different directory, the hash will be different and the cached
  291. object will not be used.
  292. To improve cache performance, set this option to y. This
  293. allows ccache to rewrite absolute paths within the output
  294. directory into relative paths. Note that only paths within the
  295. output directory will be rewritten; therefore, if you change
  296. BR2_HOST_DIR to point outside the output directory and
  297. subsequently move it to a different location, this will lead
  298. to cache misses.
