// Test --weak-unresolved-symbols.  Symbol foo remains unresolved but
// with -fPIE, needs a GOT entry and has a dynsym entry and a dynamic
// relocation against it created.  This  will fail to link and run without
// --weak-unresolved-symbols.  With --warn-unresolved-symbols, it will link
// but the dynamic linker will complain that foo(_Z3foov) is unresolved.
