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
.
