This needlessly and wastefully links in a copy of getopt on GNU systems,
where getopt already exists. There's NO reason to do that.

Can you name a system where the duplicated symbols (between the included
GNU getopt and the system's getopt) actually causes compilation
_errors_, that are difficult or impossible to work around? 

Having only a single copy and linking it into each program is good (the
only reason I added a second copy for ogg123 is that nobody else was
going to fix it, at the time, and I wasn't going to do automake crap). A
worthwhile change. 

Modifying the sources pervasively like this is definately not good,
however.
