Use autoconf check for long long in binutils
Also fix a place where %lld was wrongly used to print a dwarf_vma. * configure.ac: Check for long long and sizes of long long and long. * elfcomm.h (HOST_WIDEST_INT): Test HAVE_LONG_LONG in place of __STDC_VERSION__ and __GNUC__. * strings.c (print_strings): Likewise. * dwarf.c (DWARF_VMA_FMT, DWARF_VMA_FMT_LONG): Likewise. (read_debug_line_header): Use dwarf_vmatoa to print warning. * configure: Regenerate. * config.in: Regenerate.
