rtld: Add #if defined (__FDPIC__)

Like for other FDPIC targets, add defined(__FDPIC__) where needed.

	* include/link.h: Include bits/elf-fdpic.h if __FDPIC__ is defined.
	(link_map): Use elf32_fdpic_loadaddr if __FDPIC__ is defined.
	(dl_phdr_info): Likewise.
	* ldso/include/dl-elf.h (__dl_parse_dynamic_info): Support
	__FDPIC__.
	* ldso/include/dl-hash.h (elf_resolve): Add funcdesc_ht field if
	__FDPIC__ is defined.
	* ldso/ldso/dl-hash.c (_dl_find_hash): Support __FDPIC__.
	* libc/misc/elf/dl-iterate-phdr.c (dl_iterate_phdr): Support __FDPIC__.
