Errors due to USB_HAVE_UGEN option

[Joel Sherrill]

My suggestion is to get the complete original FreeBSD source with svn and
use something
like cscope to find the body. This appears to be a common helper and I am
surprised the
need for it hasn't turned up yet. But who knows.

Find the source in FreeBSD and make sure it is in the rtems-libbsd tree.
