Previously, when relibc/kernel/base/bootloader/installer had commits
newer than their pkgar, the script set NO_CACHE=1, which ran
'make repo_clean' and deleted the entire repo/ directory. This
forced rebuilding the full mesa/llvm21/qt6/kwin stack on every
base source change — adding 30+ minutes of wasted work to every
mini build.
Now we only delete the specific stale package's pkgar and target
dir. The cookbook rebuilds that package; downstream packages pick
up the new relibc/kernel/base via their own dependency tracking
without invalidating the rest of the repo. This is the primary
fix for the 'forever build' complaint: base source changes no
longer trigger a full mesa/llvm rebuild.
