FUNCTION
bfd_get_debug_link_info
SYNOPSIS
char *get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
char *bfd_get_debug_link_info (bfd *abfd, unsigned long *crc32_out);
DESCRIPTION
fetch the filename and CRC32 value for any separate debuginfo
associated with @var{abfd}. Return NULL if no such info found,
otherwise return filename and update @var{crc32_out}.
otherwise return filename and update @var{crc32_out}. The
returned filename is allocated with @code{malloc}; freeing it
is the responsibility of the caller.
