PR27952, Disallow ET_DYN DF_1_PIE linker input
This patch adds a new elf_tdata flag, is_pie, set during the linker's
open_input_bfds processing. The flag is then used to reject attempts
to link a PIE as if it were a shared library.

* elf-bfd.h (struct elf_obj_tdata): Add is_pie.
* elflink.c (elf_link_add_object_symbols): Set is_pie.

* ldelf.c (ldelf_after_open): Error on input PIEs too.
