x86: Suggest -fPIE when not building shared object

When PIC is needed, linker should suggest -fPIE, instead of -fPIC, when
not building shared object.

bfd/

	* elf64-x86-64.c (elf_x86_64_need_pic): Suggest -fPIE when not
	building shared object.
	* elfxx-x86.c (_bfd_x86_elf_size_dynamic_sections): Likewise.

ld/

	* testsuite/ld-i386/i386.exp: Run pr18801a and pr18801b instead
	of pr18801.
