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.
