>Environment:
host i386 box( pIII ), target mipsel. 
>Description:
SORRY, I forget to attach the module file last time.

1. compile the cross gdb target mipsel , host i386.
2. get a module .o file of mipsel, have 3 functions.
3. run gdb.
4. use command "add-symbol-file hello.o 0x10000000"
5. confirm yes.
6. use command "print my_func1" "print my_func2" "print my_func3"
7. all show the SAME address 0x10000000.

*** we meet this proble when we want to use kgdb to debug some module on mipsel board, because of this , we can't debug the module funtions, but the kernel functions seems 
all right.
the module file is attached.
>How-To-Repeat:
every time .
1. compile the cross gdb target mipsel , host i386.
2. get a module .o file of mipsel, have 3 functions.
3. run gdb.
4. use command "add-symbol-file hello.o 0x10000000"
5. confirm yes.
6. use command "print my_func1" "print my_func2" "print my_func3"
7. all show the SAME address 0x10000000.

>Fix:
I try to trace down the gdb,
it seems to read the elf symbol correctly,
the i386 native gdb doesn't have this problem.
