I'm sorry, I don't understand this question.

BFD is a library for reading and writing object files.  It supports a
number of different object file formats.

ELF is an object file format.  It is one of the object file formats
which BFD supports.

On a typical GNU/Linux system, you can get some very limited
information by running the command 'info bfd'.
