msgrcv() does not work on sparc64, as it passes the 6th argument using the ipc kludge, while the kernel waits for a 6 arguments syscall. This patches fixes the problem by using a sparc64 specific version of msgrcv.c. 2010-03-03 Aurelien Jarno <aurelien@aurel32.net> * sysdeps/unix/sysv/linux/sparc/sparc64/msgrcv.c: New file.
