[Qemu-devel] [PATCH v2 8/9] tests/docker: Kludge for missing libunistring.so symlink on Ubuntu 18.04

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

When linking statically on Ubuntu 18.04 we get:

  $ make subdir-x86_64-softmmu
  [...]
     LINK    x86_64-softmmu/qemu-system-x86_64
  c++: error: /usr/lib/x86_64-linux-gnu/libunistring.so: No such file or directory

This library is pulled in by GTK:

  $ pkg-config --libs --static gtk+-3.0
  -lgtk-3 -latk-bridge-2.0 -latspi -ldbus-1 -lpthread -lsystemd -lgdk-3 -lgio-2.0 -lXinerama -lXi -lXrandr -lXcursor -lXcomposite -lXdamage -lXfixes -lxkbcommon -lwayland-cursor -lwayland-egl -lwayland-client -lepoxy -ldl -lpangocairo-1.0 -lpangoft2-1.0 -lharfbuzz -lm -lgraphite2 -lpango-1.0 -lm -latk-1.0 -lcairo-gobject -lcairo -lz -lpixman-1 -lfontconfig -lexpat -lfreetype -lexpat -lfreetype -lpng16 -lm -lz -lm -lxcb-shm -lxcb-render -lXrender -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp -lgdk_pixbuf-2.0 -lm -lpng16 -lm -lz -lm -lz -lgio-2.0 -lz -lresolv -lselinux -lmount -lgmodule-2.0 -pthread -ldl -lgobject-2.0 -lffi -lglib-2.0 -pthread -lpcre -pthread

However, while the library is presentm, its symlink is missing:

  $ ls -ld /usr/lib/x86_64-linux-gnu/libunistring.so
  ls: cannot access '/usr/lib/x86_64-linux-gnu/libunistring.so': No such file or directory

  $ ls -ld /usr/lib/x86_64-linux-gnu/libunistring.so*
  lrwxrwxrwx. 1 root root      21 Mar  3  2018 /usr/lib/x86_64-linux-gnu/libunistring.so.2 -> libunistring.so.2.1.0
  -rw-r--r--. 1 root root 1562664 Mar  3  2018 /usr/lib/x86_64-linux-gnu/libunistring.so.2.1.0

Fix the issue by creating the missing symlink manually.
