Makese sense to me.

Until recently, there was a use in check_survey.in, but that's gone now, 
so I think your change make sense.

(We could have the DejaGNU code run "ar" to build libv3test.a, instead 
of linking in the individual objects; I just didn't, as it didn't seem 
necessary.  The primary benefit of building libv3test.a is that it would 
result in smaller test programs, as the linker would then not link in 
the objects unless they were used.)
