[SPARC64]: Fix bugs in SYSV IPC handling in 64-bit processes.
Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.
