Enable unwind info in libc-start.c and backtrace.c
Add unwind info to __libc_start_main so that unwinding continues one
extra level to _start.  Similarly add unwind info to backtrace.
Given many targets require this, do this in a general way.

	* csu/Makefile: Add -funwind-tables to libc-start.c.
	* debug/Makefile: Add -funwind-tables to backtrace.c.
	* sysdeps/aarch64/Makefile: Remove CFLAGS-backtrace.c.
	* sysdeps/arm/Makefile: Likewise.
	* sysdeps/i386/Makefile: Likewise.
	* sysdeps/m68k/Makefile: Likewise.
	* sysdeps/mips/Makefile: Likewise.
	* sysdeps/nios2/Makefile: Likewise.
	* sysdeps/sh/Makefile: Likewise.
	* sysdeps/sparc/Makefile: Likewise.
