collect2.c (main): If we have frames, then we will need to import the frame handling functions.
* collect2.c (main) [COLLECT_EXPORT_LIST]: If we have frames,
then we will need to import the frame handling functions.
(scan_prog_file) [COLLECT_EXPORT_LIST]: We will also need
to import the frames themselves.
