If the file compiles the same for all three, put CONFIG_VFIO_PCI=y into
default-configs/{i386,x86_64,ppc64}-softmmu.mak and do
hw-obj-$(CONFIG_VFIO_PCI) += in hw/Makefile.objs.

Otherwise, add to hw/{i386,ppc}/Makefile.objs - or with Anthony's
proposal from yesterday hw/Makefile.objs becomes possible, too.
