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.
