diffconfig.sh runs the configuration parser over the whole tree twice, which takes 2 s of every build, and buildinfo runs it on each build. The result depends only on .config and the Kconfig files. Skip it while neither is newer than the file it wrote last time. include/toplevel.mk guards the sync check of .config the same way. This alone changes nothing on a parallel build, because buildinfo runs beside the compile stamps. It pays once the other phases become shorter. Signed-off-by: John Crispin <john@phrozen.org>
