	* elf/elf.h: Define AT_SYSINFO_EH_FRAME.
	* sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Handle
	AT_SYSINFO_EH_FRAME.
	(_dl_show_auxv):Display AT_SYSINFO_EH_FRAME value.
	* sysdeps/generic/ldsodefs.h [NEED_DL_SYSINFO] (struct rtld_global):
	Add _dl_sysinfo_eh_frame field.
	* elf/dl-support.c [NEED_DL_SYSINFO]: Define _dl_sysinfo_eh_frame.
	* sysdeps/generic/libc-start.c [NEED_DL_SYSINFO] Define eh_obj
	variable.
	[NEED_DL_SYSINFO] (LIBC_START_MAIN): Call __register_frame_info_bases
	if _dl_sysinfo_eh_frame is non-NULL.

	* Makeconfig (gnulib): Add -lgcc_eh.

	* config.h.in: Define HAVE_FORCED_UNWIND.
