+	* configure.in: Remove --with-elf and --enable-bounded options.
+	Dont set base_machine for ia64.  More non-ELF conditions removed.
+	Remove testing and setting of leading underscore information.
+	* config.make.in (build-bounded): Set to no.
+	* config.h.in: Remove NO_UNDERSCORES entry.
+	* include/libc-symbols.h: Don't define HAVE_WEAK_SYMBOLS.  ELF has
