make -jN won't necessarily do anything when make spawns other build systems
which do their own parallelism.
(*some* systems can integrate with GNU make, see e.g.
https://github.com/ninja-build/ninja/issues/1139 )

Chromium is mostly built using their own GN system,
the backend of which actually is ninja btw
