cannot compile 2.4.19 with kgdb/xmon

[Omanakuttan]

Hi,
I am a new member in this list.
I am trying to build kernel 2.4.19 for ppc (mpc 8260) on i386 using
ppc_82xx-gcc cross compiler.

The configuration compiles fine when I exclude kernel hacking options.
Once kgdb or xmon options (any of them)  of the kernel hacking options
is included, kernel compilation fails with the following

[root at cosine-ipnos /opt/hardhat/previewkit/ppc/82xx/bin]$ ./ppc_82xx-gcc -v
./ppc_82xx-gcc: Actual path = '/opt/hardhat/previewkit/ppc/82xx/bin/'
         Actual name = 'ppc_82xx-gcc'
         Invoking
/opt/hardhat/previewkit/ppc/82xx/bin/../lib/gcc-lib/powerpc-hardhat-linux/2.95.3/ppc_82xx-gcc
Reading specs from
/opt/hardhat/previewkit/ppc/82xx/bin/../lib/gcc-lib/powerpc-hardhat-linux/2.95.3/specs
gcc version 2.95.3 20010315 (release/MontaVista)

I examined the source code and found out the function is in
/usr/src/linux-2.4.19/arch/ppc/8xx_io/uart.c but not getting compiled.
(no .o files in that dir)

Any suggestions?

Thanks and regards,
Om.
