Currently we check PTRACE_PEEKSIGINFO and if it's defined in a system
header, we suppose that ptrace_peeksiginfo_args is defined there too.
But due to a bug in glibc, this check doesn't work. Now we have F20,
where ptrace_peeksiginfo_args is defined in sys/ptrace and F21 where
it isn't defined.

Currently we clean up with wildchar mask. This actually
not that correct. Lets remove only the files were generated
by our make engine.
This as well allows to clean up objects generated as $obj-e
target even if the directory $obj-e is laying in doesn't have
own Makefile.

Makes the criu RPC socket socket-activated with
systemd [1], meaning that systemd will create and listen to
the UNIX socket /var/run/criu-srvice.socket
on behalf of criu until a connection comes in, when it will
then pass control of the socket, along with the first connection
over to a newly spawned criu daemon.
This is similar to inetd, but criu stays around after getting
started, listening itsself on the socket.

v2: stripped down sd-daemon.[ch]
moved units to scripts/sd

Defining it as static char is a bad idea especially
if it get included and never used -- we will get

In OpenVZ -> CRIU converter I use same build engine
as in criu. But converter has own specifics such as
shipping precompiled vdso.so libraries. So when I
call for "make clean" these precompiled files get
automatically deleted, which in turn cause converter
to fail on next build attempt.
Thus lets delete only *.so targets which are declared
in makefiles.

It's being reported that some systems (as Ubuntu 13.04) already
have struct tcp_repair_opt definition in their system headers.
| sk-tcp.c:25:8: error: redefinition of struct tcp_repair_opt
| sk-tcp.c:31:2: error: redeclaration of enumerator TCP_NO_QUEUE
So add a facility for compile time testing for reported entities
to be present on a system. For this we generate include/config.h
where all tested entries will lay and source code need to include
it only in places where really needed.

At moment built-in .SUFFIXES variable is not cleaned
which slows down the building procedure. Add a dummy
rule thus the make won't try to lookup rules for
scripts/Makefile.version (this happens when last
resort rule is used).
Note that this is rather a stub for future convenience
which doesn't affect much current build procedure.

and what is more important other subsystems (such as docs

for future needs.
