This fixes an error message given too eagerly on ppc64le,
when no input files are used and as-needed is in effect.  E.g.:

% ld-new --as-needed -o /dev/null -lc

gives an error message about input and output ABI versions being
incompatible.  This is because the ABI setting of "unknown" (0)
to "from-input" is done in ppc64_elf_before_check_relocs, which
isn't called for as-needed libraries (via check_directives callback).
merge_private_bfd_data is called for as-needed and not-as-needed inputs
(via notice_as_needed), so copy that code there.

This construct is used in some packages to check for availability
of libraries (e.g. in nvme-cli to check for -luuid).  Redircting error
output makes this siletently fail.
