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.
