* configure.in (libc_cv_gcc_dwarf2_unwind_info): Delete.
(HAVE_DWARF2_UNWIND_INFO{,_STATIC}): Remove AC_DEFINEs. * configure: Regenerate. * config.h.in (HAVE_DWARF2_UNWIND_INFO{,_STATIC}): Remove undefs. * elf/soinit.c: Don't include gccframe.h. (__EH_FRAME_BEGIN__): Define unconditionally. (__register_frame_info, __deregister_frame_info) (__register_frame_info_bases, __deregister_frame_info_bases) (__register_frame, __deregister_frame): Remove declarations. (__libc_global_ctors, __libc_fini): Don't call registry functions. * elf/sofini.c (__EH_FRAME_END__): Define unconditionally.
