Subject: 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.

bfd/
	PR 27952
	* elf-bfd.h (struct elf_obj_tdata): Add is_pie.
	* elflink.c (elf_link_add_object_symbols): Set is_pie.
ld/
	PR 27952
	* ldelf.c (ldelf_after_open): Error on input PIEs too.
