Hi, 

I've found a failure when building ltp-full-20090630 on powerpc:

eventfd2_03.c:48:2: error: #error Cannot detect your architecture!
eventfd2_03.c: In function ‘eventfd2’:
eventfd2_03.c:54: error: ‘__NR_eventfd2’ undeclared (first use in this function)
eventfd2_03.c:54: error: (Each undeclared identifier is reported only once
eventfd2_03.c:54: error: for each function it appears in.)
eventfd2_03.c: In function ‘main’:
eventfd2_03.c:129: warning: implicit declaration of function ‘waitpid’
make[4]: *** [eventfd2_03] Error 1
make[4]: Leaving directory `/root/ltp-full-20090630/testcases/kernel/syscalls/eventfd2'
make[3]: *** [all] Error 2
make[3]: Leaving directory `/root/ltp-full-20090630/testcases/kernel/syscalls'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/root/ltp-full-20090630/testcases/kernel'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/root/ltp-full-20090630/testcases'
make: *** [all] Error 2


This patch fixes the failure, the test program identifier and 
adds a kernel version check.
