Extended Description

In clang/lib/Driver/Tools.cpp addSanitizerDynamicList(), clang uses the --dynamic-list option, and my so check-asan in my self-hosted llvm/clang/lld test fails.

From the ld man page --dynamic-list is documented as:

   --dynamic-list=dynamic-list-file
       Specify the name of a dynamic list file to the linker.  This is
       typically used when creating shared libraries to specify a list of
       global symbols whose references shouldn't be bound to the
       definition within the shared library, or creating dynamically
       linked executables to specify a list of symbols which should be
       added to the symbol table in the executable.  This option is only
       meaningful on ELF platforms which support shared libraries.
