Change Details

I got frustrated by the amount of time that buildworld spends during make includes when doing -j1 builds to debug build failures. This change adds a new SUBDIR_WITH_INCS= variable that can be set to only run make includes on the subdirs listed in that variable or completely skip it if empty. If it is not set, it will run on all subdirs except "test" and "tests". -j1 includes step before: 70.02 real 47.59 user 16.20 sys -j8 includes step before: 18.41 real 75.07 user 29.17 sys -j1 includes step after: 15.38 real 8.63 user 4.38 sys -j8 includes step after: 5.68 real 11.41 user 7.18 sys
