x86: Properly check building shared library
If a symbol is not defined in a regular file, and we are not generating
a shared library, then set the symbol to its location in the .plt. This
is required to make function pointers compare as equal between the normal
executable and the shared library.
* elfxx-x86.c (elf_x86_allocate_dynrelocs): Check bfd_link_dll,
instead of bfd_link_pic, for building shared library.
