It took a little time on travis (I didn't measure, just starred
at build and it added not visible delay for build).
But it will help to verify that compel works on all supported arches.

C compiler might generate calls to memcpy, memset, memcmp, and memmove
as it seem fit (so far we haven't seen memmove being required). That
means we need to provide our own versions of it for code which is not
linked to a libc.
We already have a solution for that in commit bdf6051
("pie: provide memcpy/memcmp/memset for noglibc case")
but we faced another problem of compiler trying to optimize
our builtin_memset() by inserting calls to memset() which
is just an alias in our case and so it lead to infinite recursion.
This was workarounded in commit 8ea0ba7 ("string.h: fix memset
over-optimization with clang") but it's not clear that was a proper
fix.
This patch is considered to be the real solution. As we don't have
any other implementations of memset/memcpy/memcmp in non-libc case,
we can call ours without any prefixes and avoid using weak aliases.
Implementation notes:
1. mem*() functions code had to be moved from .h to .c for the functions
to be compatible with their prototypes declared in /usr/include/string.h
(i.e. "extern").
2. FORTIFY_SOURCE needed to be disabled for code not linked to libc,
because otherwise memcpy() may be replaced with a macro that expands
to __memcpy_chk() which of course can't be resolved during linking.

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.

With GNU make, using .PHONY leads to the same result as using
the "FORCE" hack, but unlike FORCE is not a hack. Since we do not
plan to use any other make than GNU make, let's just mark phony
targets as such.
