sh: Workaround for __put_user_asm() bug with gcc 4.x on big-endian.
I think this problem is GCC(4.1.2) bug. Syscall "getdents" returned "dirent->d_off" is always 0. I think other EB enviroment have same problem. Problem code 0c03c954 <filldir>: : c03c97a: 58 f7 mov.l @(28,r15),r8 !-> offset (high) c03c97c: 59 f8 mov.l @(32,r15),r9 !-> offset (low) c03c97e: 53 f9 mov.l @(36,r15),r3 c03c980: 54 fa mov.l @(40,r15),r4 : c03c9a0: 21 82 mov.l r8,@r1 !offset(high) -> dirent->d_off It's workaround patch.
