Using cross compiled GDB under Emacs

[Dmytro Bablinyuk <dmytro.bablinyuk@rftechnology.com.au>]

I have cross compiled gdb and I can set a break point under emacs using 
'C-x space' but when gdb stops at breakpoint Emacs does not show the 
line where gdb stopped. If I use 'b' command - the same, Emacs does not 
show the file and line where it stopped. If I try to see line info it 
says that no line number available.
Here is dump:

There is absolutely no warranty for GDB.  Type "show warranty" for details.
This GDB was configured as "--host=i386-pc-linux-gnu 
--target=powerpc-linux-uclibc"...0xfff00100 in ?? ()

(gdb) ram
add symbol table from file "u-boot" at
	.text_addr = 0x3fc7000
(gdb) b board_init_r
Breakpoint 1 at 0x3fcba28: file board.c, line 588.
(gdb) c
Continuing.

Breakpoint 1, <signal handler called>
(gdb) info line
No line number information available.
(gdb)

Does anybody know how to 'attach' emacs to gdb?
The program was compiled with these options
-ggdb  -Os   -fPIC -ffixed-r14 -meabi -D__KERNEL__ 
-DTEXT_BASE=0xFFF00000 -fno-builtin -ffreestanding -nostdinc -isystem 
-pipe  -DCONFIG_PPC -D__powerpc__ -DCONFIG_8260 -DCONFIG_CPM2 -ffixed-r2 
-ffixed-r29 -mstring -mcpu=603e -mmultiple -Wall -Wstrict-prototypes

Thank you
