It seems that at least parts of druntime gets included in the Phobos 
library.  Here is the line (200) from the Phobos makefile that builds the 
file libphobos2.a:

  $(DMD) $(DFLAGS) -lib -of$@ $(DRUNTIME) $(D_FILES) $(OBJS)

The variable $(DRUNTIME) contains the path to libdruntime.a.  If it is 
removed, Phobos still compiles just fine, so I suspect it shouldn't be 
there.
