* emultempl/aix.em (export_files): Remove.
(import_files): Make static.
(struct export_symbol_list): Define.
(export_symbols): New static variable.
(gld${EMULATION_NAME}_parse_args): Handle an initial -b option
correctly. Call read_file for an export file.
(gld${EMULATION_NAME}_before_allocation): Call
bfd_xcoff_export_symbol for each export symbol, rather than
calling read_file for each export file.
(gld${EMULATION_NAME}_read_file): For an export file, make the
exported symbols undefined, and store them on the export_symbols
list.
