Oops, actually, swap the order of libfoo.so and libbar.so on the last command
line and then it is a regression from older binutils (e.g. 2.16.91.0.6 
20060212).

echo 'int foo1;' | gcc -shared -fpic -o /usr/lib/libfoo.so -xc - -xnone \
  -Wl,-soname,libfoo.so
echo 'int foo1; int foo2;' | gcc -shared -fpic -o libfoo.so -xc - -xnone \
  -Wl,-soname,libfoo.so
echo 'int foo (void) { extern int foo2; return foo2; }' \
  | gcc -shared -fpic -o libbar.so -xc - -xnone ./libfoo.so
echo 'extern int foo (void); int main (void) { return foo (); }' \
   | gcc -o test -xc - -xnone -Wl,--as-needed ./libbar.so ./libfoo.so \ 
     -Wl,--no-as-needed
