these should be rebuilt via the generated header dependencies; for a lot 
of your examples the relevant file is
  workdir/Dep/LinkTarget/Library/libsclo.a.d

this should contain e.g. a dependency from sc/.../xiescher.o to whatever 
header declares class ScNoteUtil.

there are 2 ways to generate these .d files, one is in 
gb_LinkTarget__command_impl (shortcut as a side effect of linking) and 
the other is gb_LinkTarget__command_dep which will be invoked if the 
linking step didn't happen on the next invocation of make.

oh, there is one configure option that disables this whole thing, you 
can shoot yourself in the foot with --disable-dependency-tracking.

the examples relating to functions defined in libsc*.a should definitely 
not happen even if you do only a module local build (make sc).
