The GNUmakefile is unsupported and is provided by Richard as a convenience for 
GNUstep developers.  

If you want to install libobjc into your GNUstep paths then you can set the 
correct variables.  I haven't looked at the GNUmakefile for a long time, but I 
was under the impression that this is what it did - pick up your library and 
header paths and then pass these to a sub invocation of Make.

GNUstep Make is very good when you want to do things that it anticipated, but 
very hard to modify.  The linkage requirements of libobjcxx are very difficult 
to express because they conflict with its assumptions.  The Makefile is a 
simple, portable build system that should work on any
