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.
