Sorry just tested this more thoroughly - it seems you will also need to 
edit include/Make/Grass.make.in and change
IOSTREAMDEP = $(ARCH_LIBDIR)/$(LIB_PREFIX)$(IOSTREAM_LIBNAME)$(LIB_SUFFIX)
to
IOSTREAMDEP = $(ARCH_LIBDIR)/$(LIB_PREFIX)$(IOSTREAM_LIBNAME)$(STLIB_SUFFIX)
and then rerun the configure script, in order for r.terraflow to compile 
properly.
