The Check test framework forks by default which is annoying when running gdb. Try to detect whether we're inside gdb by ptracing ourselves. If that works, we're not inside a debugger. If it doesn't, then assume we're inside a debugger and set CK_FORK to "no". Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
