Pass link_info to _bfd_merge_private_bfd_data

Most BFD linker functions take a bfd_link_info param, which reinforces
the fact that they are linker functions and allow access to linker
callbacks, eg. einfo for printing errors.  I was going to use einfo
for --fatal-warnings support before I decided a better way was the
patch commit 4519d071.
