Yes. I saw that problem, too. This patch for Makefile fixed it for me:

index ccab967,a28a3c8..8ec3a99
@@@ -170,6 -159,6 +170,7 @@@ qemu-options.def: $(SRC_PATH)/qemu-opti
  SUBDIR_RULES=$(patsubst %,subdir-%, $(TARGET_DIRS))
  SOFTMMU_SUBDIR_RULES=$(filter %-softmmu,$(SUBDIR_RULES))

++$(SOFTMMU_SUBDIR_RULES): $(block-obj-y)
  $(SOFTMMU_SUBDIR_RULES): config-all-devices.mak

  subdir-%:
