The second process has not a file descriptor for the ctl tty,
but this tty is opened in tty03.
Currently CRIU can not restore this test case correctly.

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.
Currently I know only one difference between these types, it's
O_LARGEFILE.

Generate random data only for buffers with sizes less than FAST_SIZE
If a size of buffer is more that FAST_SIZE, the first FAST_SIZE bytes
are filled by random generator and then this chunk is used as pattern
for all other chunks.

A signal can be handled by non-leader thread and sigsuspend

kill can send signals to a specified thread, so a futex is used for

To be able to test it one need indeed enough
physical memory on the node (at least 16G).
Thus I don't include this test for regular

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.
