The gcc might inline kgdb_breakpoint() which includes
arch_kgdb_breakpoint().  I got this error with gcc 4.3.1:

  CC      kernel/kgdb.o
{standard input}: Assembler messages:
{standard input}:809: Error: symbol `breakinst' is already defined
{standard input}:913: Error: symbol `breakinst' is already defined
{standard input}:1233: Error: symbol `breakinst' is already defined

Moving arch_kgdb_breakpoint() into arch/mips/kernel/kgdb.c should
solve the problem.
