Sure can.  Create a file (let's call it foo.c)... it just contains:

     int foo_tester()
     {
          return(twenty());
     }

Then run the following:

     gcc -fPIC -c foo.c

After the compilation, run:

     gcc -shared -o libfoo.so foo.o
     gcc -shared -Wl,-Bsymbolic -o libfoo.so foo.o
     gcc -shared -Wl,--noinhibit-exec -Wl,-Bsymbolic -o libfoo.so foo.o

On Intel, the first succeeds, the second fails (as expected), and the
third succeeds in building a .so file, even with the "undefined
reference" error.

On PPC, the first succeeds, but the second and third both fail.
