PR gold/5986
Fix problems building gold with gcc 4.3.0.
* gold.h (TEMPLATE_ATTRIBUTE_PRINTF_4): Define.
(gold_error_at_location, gold_warning_at_location): Use it.
* configure.ac: Check whether we can compile and use a template
function with a printf attribute.
* x86_64.cc (Target_x86_64::do_code_fill): Swap out a 32-bit value
when jumping over bytes.
* object.cc: Instantiate Object::read_section_data.
* debug.h: Include <cstring>
* dwarf_reader.cc: Include <algorithm>
* main.cc: Include <cstring>.
* options.cc: Include <cstring>.
* output.cc: Include <cstring>.
* script.cc: Include <cstring>.
* script.h: Include <string>.
* symtab.cc: Include <cstring> and <algorithm>.
* target-select.cc: Include <cstring>.
