in __ARCH_WANT_SYSCALL_DEPRECATED, asm-generic/unistd.h haven't define __NR_ipc and __NR__llseek which used in glibc.
Now we have maintained 3 sets of syscall API code use for glibc. 1: Old syscall interface, which linux/score system work well. 2: New syscall interface, define all 4 macro __ARCH_WANT_SYSCALL_XXX, linux/score system work now, but we still debug the glibc code. 3: New syscall interface, without define __ARCH_WANT_SYSCALL_DEPRECATED and __ARCH_WANT_SYSCALL_OFF_T, linux/score system couldn't work. because glibc have many place need to fix.
