20 SONAME_MOVE in tst-sonamemove-runmod1.so, using the

23 At run time, the process loads the real tst-sonamemove-runmod1.so,
24 which depends on tst-sonamemove-runmod2.so.
25 tst-sonamemove-runmod1.so does not define moved_function, but
26 tst-sonamemove-runmod2.so does.

29 moved_function@SONAME_MOVE moved from the soname
30 tst-sonamemove-linkmod1.so at link time to the soname
31 tst-sonamemove-linkmod2.so at run time. */
