The current objc-runtime flag sets 1.8

If you are talking about overriding normal behavior, gnustep, make already 
provides the abiliity to filter out flags (even for individual files), so I 
expect you could add the option in your individual make file to filter out the 
1.8 setting and add a 2.0 setting.

On the other hand, if you just want a quick global change in gnustep-make 
behavior then edit library-combo.make to say 2.0 rather than 1.8

If you are talking about changing the normal behavior for everyone, using 
autoconf is the way to do that ... the autoconf script should, at configure 
time, execute macros to determine what runtime version your compiler/runtime 
support.  It would then generate the makefiles to use that version.
