The pipe retrieving shared libraries the test depends on
ldd $test_path $ps_path | awk '/^\s/{ print $1 }'
doesn't actually produce any output so all NS tests fail
bacause the system linker fails to locate shared libraries
the test program depends on. This patch fixes the pipe
to retrieve the list of libraries properly.

Before this patch crtools/test is bound to crtools/test/dump/crtools.XXXXXXX
It's a main reason why "make clean" deletes all content from crtools/test.
Always when you have a test bind mount. You have a test bind mount, when
a test is executed. You execute a test sometimes. So "make clean"
deletes all content sometimes;).
This patch fixes this problem.
Actually this patch fixes more significan problem. If / is a shared
mount (it's defult in FC19),
$ mount --bind crtools/test crtools/test/dump/crtools.XXXXXXX
will recursively copy all previous bind mounts.
E.g:
cd crtools/test
make -j 4

If a master point has sid, it doesn't mean, that all slave points
will have sid. Look at tty03 for example:
PID SID TT COMMAND
26748 26748 ? tty03
26749 26749 pts/2 \_ tty03
26750 26750 ? \_ tty03
The second process has not a file descriptor for the ctl tty,
but this tty is opened in tty03.
v2: If a slave point with sid has not a master point, the option
--shell-job must be set and sid isn't restored for such terminals.

The system call open can add O_LARGEFILE.
A point is reopend for unsharing a file descriptor. So here are two
types of points. One is returned by pipe() and all other ones are
got via opening /proc/PID/fd.

O_LARGEFILE.

In case if only "dump" procedure is invoked we left service
"link_remap.%d" file(s) on disk. This prevents next "dump"
procedure of same test to fail because we hit the situation
where same named "link_remap.%d" already exist.
So, if test is passed with "-d" option we remove the link remap
file at the end.
Also with this patch we start passing --link-remap option
only for tests which have "unlink_" prefix in name. This applies
some limitation on how test could be named, thus maybe we need
more flexible solution here.

Andrew Vagin pointed out that the static testsuite compilation
may run as standalone so the variable ARCH won't be available.
This patch introduces the facility test/zdtm/Makefile.inc
designated to detect the target machine automatically
if the variable ARCH isn't defined. This makefile is supposed
to be included into all test subsuite Makefiles.
Andrew Vagin also pointed out that machine-dependent tests
may be added into non-static subsuites as well so the macro
adding machine-specific headers into CPPFLAGS goes to
the file test/zdtm/Makefile.inc.
