Well, obj-y is for the current target that gets compiled. But if you use
it in a Makefile that gets used by all targets, the file gets compiled
for each target individually.
Just try to change "obj-$(CONFIG_ARM_V7M) += armv7m_nvic.o" into
"obj-y += armv7m_nvic.o" in hw/int/Makefile.objs, and you'll see it break:
CC alpha-softmmu/hw/intc/armv7m_nvic.o
In file included from include/hw/intc/armv7m_nvic.h:13,
from hw/intc/armv7m_nvic.c:19:
target/arm/cpu.h:1416: error: "FPCR_DZE" redefined [-Werror]
