 Add a compile option to turn off all the compiled in help
 and usage information.  Some folks don't need or want it...

+Running the following:

+It would be a very nice thing to reduce this list to an absolute minimum, and
+then create a microLibc to provide these functions.  There is no good reason
+for GNU libc to be so big.  I'm sure it can be a lot better.

 Compile with debugging on, run 'nm --size-sort ./busybox'
