It would be nice to keep 'module_name' of type 'char *', because it is a
string.

The declaration of bfd_get_section_contents is,
bfd_boolean bfd_get_section_contents
(bfd *abfd, asection *section, void *location, file_ptr offset,
bfd_size_type count);
the parameter 'location' 's type is 'void *', do we really need to cast
'buf' to 'bfd_byte *'?
