Indirectly it's possible, with something like

$(common-obj-y): QEMU_CFLAGS += -include exec/poison.h

It's very similar to what we do already in fact:

QEMU_CFLAGS += -I.. -I$(SRC_PATH)/target-$(TARGET_BASE_ARCH) -DNEED_CPU_H

is in Makefile.target, and $(common-obj-y) is compiled outside
Makefile.target so it doesn't get NEED_CPU_H.
