This breaks with my patchset to split out the arm7 code to an SPL
because even though SRCDIR and OBJDIR are the same, in the SPL build
$(obj) is a subdir of $(SPLTREE) not $(OBJTREE) (not my doing).

How about the following instead which seems more to the point:

ifeq ($(wildcard $(obj)../common),)
$(shell mkdir -p $(obj)../common)
endif
ifeq ($(wildcard $(obj)../../nvidia/common),)
$(shell mkdir -p $(obj)../../nvidia/common)
endif
