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

At run time, the process loads the real tst-sonamemove-runmod1.so,

tst-sonamemove-runmod1.so does not define moved_function, but

tst-sonamemove-runmod2.so does.

The net effect is that the versioned symbol

moved_function@SONAME_MOVE moved from the soname

tst-sonamemove-linkmod1.so at link time to the soname

tst-sonamemove-linkmod2.so at run time. */
