You would force it by defining the Makefile macro XDR_LIBOBJS in the
xdr/ subdirectory to be a blank seperated list of all possible .o (object) 
files in the xdr subdirectory with the exception of xdrtest (this would
be the relocatable for an executable, not a part of the library).

A quick follow-up comment about doing this on a Cray.  We don't believe that
this is what you want to do since the XDR package that we distribute does
not understand the Cray floating point format (nor 64-bit integers for that
matter) format.  If you decide to override the use of your Cray-native XDR 
implementation, you will undoubtedly need to do a lot of work on the xdr source
in order to make things work.  We strongly suggest NOT doing this.
