objc runtime: cannot find class Test

So this is the real problem. The compiler apparently produces an executable for
the source file, but when running it it doesn't find the Test class (which is
defined in config/config.objc.m). Not sure why this happens.
I tried building the test standalone I can reproduce the error (just
building config.objc.m). The problem reproduces:
grid$ ./conftest
objc runtime: cannot find class Test
[1] Abort trap (core dumped) ./conftest
the stacktrace doesn't reveal anything useful to my eyes:
#0 0xbbb37c17 in _lwp_kill () from /usr/lib/libc.so.12
#1 0xbbb37bb6 in raise () from /usr/lib/libc.so.12

#6 0x080489a5 in main () at config.objc.m:21
Did I manage to get a broken runtime? I hope not. I wonder what could be
going bad here.
I reduced the compile line to:
gcc -o conftest -g -O2 -fgnu-runtime -x objective-c config.objc.m
-lrt -lpthread -rdynamic -shared-libgcc -pthread -fexceptions
-fgnu-runtime -lobjc -lm
since we do not need all the headers and libraries anyway (and the
compiler is much faster! wow!). However, same error :(
