[PATCH] clean up kernel messages
Arrange for all kernel printks to be no-ops.  Only available if
CONFIG_EMBEDDED.

This patch saves about 375k on my laptop config and nearly 100k on minimal
configs.

+	  This option enables normal printk support. Removing it
+	  eliminates most of the message strings from the kernel image
