* gold.h (gold_undefined_symbol): Change to take only a Symbol pointer and to report location as the file name associated with the symbol. (gold_undefined_symbol_at_location): New function to replace the old gold_undefined_symbol functionality. * target-reloc.h (relocate_section): Update to use gold_undefined_symbol_at_location. * symtab.cc (Symbol_table::warn_about_undefined_dynobj_symbol): Call gold_undefined_symbol function rather than gold_error. * errors.h (Errors::undefined_symbol): Take location as a string, rather than calculating it from a relocation. * errors.cc (Errors::fatal): Print "fatal error:" before the formatted message. (Errors::error, Errors::error_at_location): Print "error: " before the formatted message. (Errors::undefined_symbol): Take location as a string, rather than calculating it from a relocation. (gold_undefined_symbol_at_location): New function akin to old gold_undefined_symbol, calculates location from relocation. (gold_undefined_symbol): Change to take only a Symbol pointer and to report location as the file name associated with the symbol. * testsuite/debug_msg.sh: Update for changed error messages. * testsuite/undef_symbol.sh: Likewise.
