Comment (by thomie):

 In `compiler/main/DriverPipeline.hs`:
 {{{
 linkingNeeded :: DynFlags -> Bool -> [Linkable] -> [UnitId] -> IO Bool
 linkingNeeded dflags staticLink linkables pkg_deps = do
          -- if the modification time on the executable is later than the
          -- modification times on all of the objects and libraries, then
 omit
          -- linking (unless the -fforce-recomp flag was given).
 ...
 }}}
