[Bug 1878348] Re: --static build fails in v5.0 (since 5010cec2bc87dafab39b3913c8ca91f88df9c540)

[Peter Maydell]

Some people want the system emulation to be statically linked, which is
why we don't refuse to do it entirely; and static vs not changes a bunch
of stuff like CFLAGS which we assume to be common across the whole
build. So if you want some statically linked binaries and some not
statically linked, then yes, you should configure and build twice. (Use
separate build directories, one for each config.)

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
