[obv] testsuite: disp-step-syscall.exp: Setup KFAIL for PR server/13796

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

[patch] Fix disp-step-syscall.exp on some i386 targets
http://sourceware.org/ml/gdb-patches/2012-02/msg00635.html

just fixed a testcase which revealed existing IMO gdbserver Bug, therefore
just KFAILed it.

stepi
Program terminated with signal SIGILL, Illegal instruction.
The program no longer exists.
(gdb) PASS: gdb.base/disp-step-syscall.exp: vfork: single step over vfork
Child terminated with signal = 0x4 (SIGILL)
GDBserver exiting
print /x $pc
No registers.
(gdb) FAIL: gdb.base/disp-step-syscall.exp: vfork: get hexadecimal valueof "$pc" (timeout)

Regards,
