Supply the actual compiler output.
Do you really have a file named libSDL-1.2.so.<something> in any directory that you're adding with the -L flag?
This lines looks weird:
CFLAGS += -I$(COMPILER_DIR)/arm-none-linux-gnueabi/libc/lib
-I is used to add directories for #include operations. libc/lib looks like a place with dynamically linkable libraries.

Yes I have here LDFLAGS = -L/scratchbox/users/figa/targets/FREMANTLE_ARMEL/usr/lib Ok I changed it, but still doesn´t work.

Again, supply the actual compiler output. You're only showing the last step with linking.
To actually see all flags and their values, it would help to see what is done.

Sorry.

This
would, in my eyes, look more proper like this
Where are SDL_LIBS and LIBGL_LIBS defined? It looks like you didn't show the right makefile.
To help the linker, you can use -l:libSDL-1.2.so.0 to give the full name of the library you want to link against.
You should also note that when compiling C++ code, CXXFLAGS is typically used and there are already rules built into make to handle .cpp => .o files. Try to write as few rules of your own as possible and use the proper variables instead.
Code:
gles2n64.$(SO_EXTENSION): $(OBJECTS) $(CXX) $^ $(LDFLAGS) $(SDL_LIBS) $(LIBGL_LIBS) -shared -o $@
Code:
gles2n64.$(SO_EXTENSION): $(OBJECTS) $(CXX) $(LDFLAGS) $(SDL_LIBS) $(LIBGL_LIBS) -shared -o $@ $^
