--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
--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.

The --dynamic-list* options are intended for shared libraries.  The goal
IS NOT put them in dynamic symbol table since all global symbols are in
dynamic symbol table already in a shared library.  The goal is to make
them PREEMPTIBLE.  So making the --dynamic-list* options override -Bsymbolic
and -Bsymbolic-functions is incorrect since there is NOTHING to override.
