    elf: Fix tests that require interposable symbols
    
    clang defaults to -fsemantic-interposition, which in turn trigger some
    optimizations (like inline) that makes some tests that rely on ELF
    symbol interposition to fail.  For this case, explicit set the symbol as
    weak to avoid it.
