* configure.ac: Check for link.h and dl_iterate_phdr.
* elf.c: #include <link.h> if system has dl_iterate_phdr. #undef
ELF macros before #defining them.
(dl_phdr_info, dl_iterate_phdr): Define if system does not have
dl_iterate_phdr.
(struct elf_syminfo_data): Add next field.
(elf_initialize_syminfo): Initialize next field.
(elf_add_syminfo_data): New static function.
(elf_add): New static function, broken out of
backtrace_initialize. Call backtrace_dwarf_add instead of
backtrace_dwarf_initialize.
(struct phdr_data): Define.
(phdr_callback): New static function.
(backtrace_initialize): Call elf_add.
* dwarf.c (struct dwarf_data): Add next and base_address fields.
(add_unit_addr): Add base_address parameter. Change all callers.
(add_unit_ranges, build_address_map): Likewise.
(add_line): Add ddata parameter. Change all callers.
(read_line_program, add_function_range): Likewise.
(dwarf_lookup_pc): New static function, broken out of
dwarf_fileline.
(dwarf_fileline): Call dwarf_lookup_pc.
