"it really can compile on my computer" means when I press make, the lines:
CC x86_64-softmmu/hw/xen/xen_pt_config_init.o
LINK x86_64-softmmu/qemu-system-x86_64

I am not sure before, I am not aware of this before:-[ this time, I did
with:
$ ./configure --enable-debug --enable-xen-pci-passthrough
--target-list=x86_64-softmmu
$ make clean; make
It can compile. Then I checked x86_64-softmmu/config-target.mak: the
CONFIG_XEN_PCI_PASSTHROUGH=y does exist.
