// File 1 in shared library, file 2 in executable.
// Files 1 and 2 linked together in shared library.
// Files 1 and 2 in different shared libraries.
// We test the following cases.
// 1 Code in file 1 calls code in file 2.
// 2 Code in file 1 refers to global data in file 2.
// 3 Code in file 1 referes to common symbol in file 2.
// 4 Code in file 1 refers to offset within global data in file 2.
