With this, one can do a CRUI build via QEMU+Docker using clang
as a compiler, for example:
make -C scripts/build alpine-clang
make -C scripts/build ppc64le-clang
For alpine, default clang version is used. For others, a version has
to be specified explicitly, as there is no package called "clang" in
Ubuntu Trusty (which is used as a base for most arches). Since
clang-3.8 appears to be available from Trusty, and this is the current
stable version of clang, let's use it.

I just spent some considerable time trying to figure out the source
of errors like this:
make -C scripts/build ppc64
...
DEP images/autofs.pb-c.d
In file included from images/autofs.pb-c.c:9:0:
images/autofs.pb-c.h:7:35: fatal error: protobuf-c/protobuf-c.h:
No such file or directory
#include <protobuf-c/protobuf-c.h>
^
compilation terminated.
It appears that we copy the complete tree to a docker container, and it
is not cleaned properly before the build. In particular, images/*.pb-c.{c,h}
are not removed/rebuilt. The problem is not noticeable until version of
protobuf-c differs between the host and container, and they use different
include paths (/usr/include/google/protobuf-c/ vs /usr/include/protobuf-c).
As I don't want anyone else to spend so much time figuring this out,
here is the patch.

git is needed as the top-level Makefile calls it. Strictly speaking
git is not required to build CRIU, but it's better to have it than
to see some error messages.
coreutils is needed for nproc utility which is called from Dockerfile:
make -j $(nproc)
Before this patch, it was equivalent to "make -j" (plus an error
message) which is not the best thing to do.
