Add regression test for #10110.

Module C imports a from Module A and b from module B. B does not
import anything from A. So if ld is configured to drop DT_NEEDED
tags for libraries it does not depend on no DT_NEEDED tag for the
temporary shared object containing module A is recorded in the temp
SO containing module B. This leads to an undefined symbol when
linking the temp SO for module C.

Fixes #10110.
