strip -R .ident -R .comment -R .note

is your friend. 

Or if we would like to solve it more elegant:

--- linux-2.4.10/arch/i386/vmlinux.lds       Tue Oct  9 16:36:06 2001
+++ linux/arch/i386/vmlinux.lds   Tue Oct  9 16:36:28 2001

        *(.exitcall.exit)

        }

   /* Stabs debugging sections.  */

which puts it into the list of sections to be discarde on i386.
