* peXXigen.c (pe_print_resource_entries): New function: Displays
an entry in a .rsrc section. (pe_print_resource_directory): New function: Displays a directory in a .rsrc section. (pe_print_rsrc): New function: Displays the contents of .rsrc section. (_bfd_XX_print_private_bfd_data_common): Call pe_print_rsrc. * binutils-all/windres/windres.exp: Run for x86_64-pc-cygwin. Add test of "objump -p" output.
