* pe-dll.c : Fix typo.

  (autofilter_symbolprefixlist) : Remove __imp_.
  (is_import) : New.
  (auto-export) : Remove  re-import check. Moved to callers.
  (process_def_file) : Check is symbol is an import. Always underscore __imp_.
  Only skip underscore on underscored targets.
  (make_one) : Always underscore __imp_.
  (pe_create_runtime_relocator_reference) : Only underscore _pei386_runtime_relocator on underscored targets.
  (pe_process_import_defs) : Always underscore __imp_.
* pe.em (U) : New macro.
  (set_pe_subsystem) : Remove underscore from _WinMainCRTStartup on wince subsystem case.
  (pe_find_data_imports) : Use U on "_head_".
  (gld_${EMULATION_NAME}_unrecognized_file) : Use U.
