This option prints the name of the DLL that gets imported, when linking against an import library. This is implemented using the same strategy as GNU dlltool does; looking for the contents of .idata$6 or .idata$7 chunks. The right section name to check for is chosen by identifying whether the library is GNU or LLVM style. In the case of GNU import libraries, the DLL name is in an .idata$7 chunk. However there are also other chunks with that section name (for entries for the IAT or ILT); identify these by looking for whether a chunk contains relocations. Alternatively, one could also just look for .idata$2 chunks, look for relocations at the right offset, and locate data at the symbol that the relocation points at (which may be in the same or in another object file).
