[PATCH][MIPS] kernel build fails if CONFIG_KGDB=y and CONFIG_SMP=n

[Frank Rowand <frank.rowand@am.sony.com>]

The kernel build fails if CONFIG_KGDB=y and CONFIG_SMP=n.

kgdb_wait() is defined but unused, resulting in a warning.
The warning is converted to an error by the
"EXTRA_CFLAGS += -Werror" in arch/mips/kernel/Makefile.
