There was a time when I thought thought supporting non-dwarf2 capable
debuggers with the UDK taret would have been useful.   Since the UDK 
ships with a debugger that groks dwarf2 and doesn't even pretend to work
with older debuggers, I decided that position was fine for EGCS, too.

I removed the explicit override from udk.h.

I know that pointing to bad examples doesn't make it right but when I 
originally decided not to put one on sysv5.h it was becuase other files
in config/i386.h that were short (esp. those that were essentially wrappers)
didn't have a notice at the top.

That said, I inserted one and committed it.
