## Check interaction between -rename_section and -rename_segment.
## rename_segment should be applied after rename_section, so the output
## name of rename_section is renamed by rename_segment.
## (ld64 leaves an empty __TO_SECT,__to_sect in the output for the intermediate
## name, but it too writes the actual data to __SEG,__to_sect.)
