GNUstep base fails - libobjc2 on NetBSD x86

Hi,

I am still struggling to get GNUstep running on NetBSD/i386... strange 
thing. I am trying to get it runing with libobjc2. I just updated that 
one too.
WIth David some fixes where done in libobjc2 some weeks ago.

make:
   $ ./configure --with-library-combo=ng-gnu-gnu prefix=/ 
--with-layout=gnustep


I configured libobcj2 with:
  CMAKE_C_FLAGS                    -march=i686 -mtune=i686


the arch is to avoid atomics issues on NetBSD.

I tried both the bfd and the cold linker.... no help

Currently I fail with:
configure:7872: checking whether objc really works

any ideas?
