[PATCH] kbuild: revert "fix make -jN with multiple targets with O=..."
Commit 296e0855b0f9a4ec9be17106ac541745a55b2ce1:
"kbuild: fix make -jN with multiple targets with O=..."
causes a ~95% increase in build time for the kernel. Before: 4m21s
after: 8m1.403s. Can we revert this until another approach is found?
