That would seem to suggest you have gnustep-make trying to use clang and the 
new runtime but gnustep-base expecting to use gcc and the gnu runtime.
Could it be that you forgot to set the library combo for the modern 
compiler/runtime rather than the traditional one? 
The gnustep-base configure script should recognise the library combo (from the 
environment or from gnustep-make) when figuring out how to configure itself;
traditional (gnu runtime in the library combo) implies traditional abi
modern, next-generation (ng runtime in the library combo) implies the 
nonfragile abi
