I think it's largely that many distros ship pkg-config files which are
just broken for the static linking case -- so configure tests "does pkg-
config say this will work for static linking", and pkg-config says "yes,
that will work", and then it doesn't. If you care about trying to get
this to be more reliable you'd want to investigate all of these and file
bugs upstream with your distro and get them fixed...

Bug description:
  Hi,

  Since commit 5010cec2bc87dafab39b3913c8ca91f88df9c540, building qemu
  fails when configured with --static (eg ../configure --target-
  list=x86_64-softmmu,x86_64-linux-user --enable-debug --static).

  On ubuntu 16.04, it fails to find -lffi and -lselinux.

  After I apt-get install libffi-dev libselinux1-dev, the build still fails:
  ../backends/dbus-vmstate.o: In function 
`_nocheck__trace_dbus_vmstate_pre_save':
  /home/christophe.lyon/src/qemu/build-static/backends/trace.h:29: undefined 
reference to `_TRACE_DBUS_VMSTATE_PRE_SAVE_DSTATE'
  ../backends/dbus-vmstate.o: In function 
`_nocheck__trace_dbus_vmstate_post_load':
  /home/christophe.lyon/src/qemu/build-static/backends/trace.h:52: undefined
