You are asking for very basic debugging advice, which is likely why no
one has responded.

First, objdump -i to make sure you compiled in the required object
support, then put breakpoints on the BFD_SEND_FMT calls in
bfd_check_format_matches.  Trace through the one you think should
match (look at abfd->xvec to see what is attempted).
