[racket] Racket without thread-local storage?

Hi. I have this issue when I compile racket with GCC 4.2 on OpenBSD:

cd ../foreign; make all
make foreign.lo
/usr/bin/libtool --mode=compile --tag=CC cc -O2 -pipe -g 
-I/usr/local/include -I/usr/X11R6/include -DMZ_USE_JIT_SSE 
-I/usr/local/include -pthread    -DMZ_USES_SHARED_LIB  -I./../racket 
-I/usr/ports/pobj/racket-5.3.3/racket-5.3.3/src/foreign/../racket/include -I/usr/ports/pobj/racket-5.3.3/racket-5.3.3/src/foreign/../racket/src 
   -c /usr/ports/pobj/racket-5.3.3/racket-5.3.3/src/foreign/foreign.c -o 
foreign.lo
cc -O2 -pipe -g -I/usr/local/include -I/usr/X11R6/include

-c /usr/ports/pobj/racket-5.3.3/racket-5.3.3/src/foreign/foreign.c -fPIC 
-DPIC -o .libs/foreign.o

I know the problem is the lack of support for TLS on OpenBSD/GCC. Now I 
compile racket with GCC 4.6 because this version has TLS support 
emulated but I think this workaround is adding other bugs to racket. Is 
it possible to compile racket in a OS/compiler without thread-local 
storage?.

My configure options: --enable-libffi --enable-gracket --enable-jit 
--enable-foreign --enable-places --enable-float --enable-docs 
--enable-pthread --enable-lt=/usr/bin/libtool --enable-futures
