[CRIU] [PATCH] crtools: add Dockerfile to build criu on armv7hf, aarch64, ppc64le

[Laurent Dufour]

Hi Andrew,

The root cause of the issue is that signal handler is not properly
handled in the qemu-user version installed from the debian repository.
In this release signal frame was never built when a signal is caught by
the emulated process which is fatal.

I build the qemu-user-ppc64le from the Qemu's git tree and I could
successfully run the docker command to build criu.

It seems to be fixed since Qemu 2.2.0. May be should you change the
extract-deb-pkg script to retrieve an earlier release ?

By the way there is a little typo in the Makefile:

@@ -15,7 +15,7 @@ aarch64: qemu-user-static
        docker build  -t criu-aarch64 -f Dockerfile.aarch64 ../..

 ppc64le: qemu-user-static
-       docker build  -t criu-aarch64 -f Dockerfile.ppc64le ../..
+       docker build  -t criu-ppc64le -f Dockerfile.ppc64le ../..

And I had to add "pkg-config" to the list of the installed package in
the docker's image.

Cheers,
Laurent.
