[PATCH] makefiles: Avoid rpath=$ORIGIN/... on NetBSD.

[Francois Gouget]

On NetBSD using $ORIGIN in an rpath does not work when running the
executable from a symbolic link located in another directory. This is
probably because $ORIGIN is set from /proc/self/exe which contains the
paths of the symbolic link instead of that of the executable, resulting
in the rpath pointing to the wrong location.

For Wine this means running './wine notepad' from a 64 bit build does
not work because libwine.so.1 is not found.

So avoid $ORIGIN on NetBSD and instead use the full path to the build
directory. At least this will work until the build directory is moved
around.

I don't really like this patch but it gets things going. I consider it 
to be a NetBSD bug and ideally they would fix it. But then we need some 
solution in the interim. Also the NetBSD developers seem to dislike the 
$ORIGIN feature so I'm not sure that will happen.
