Add optional verbose debug - which when turned off, quiets down
userspace errors. Saves ~8k of code/data for production systems

+          When a program crashes due to an exception, or the kernel detects
+          an internal error, the kernel can print a not so brief message
+          explaining what the problem was. This debugging information is
+          useful to developers and kernel hackers when tracking down problems,
+          but mostly meaningless to other people. This is always helpful for
+          debugging but serves no purpose on a production system.
+          Most people should say N here.
