Alexey, what will we do when Fedora and other major distributions
switch to gold(1)?
We have three options:

1. Switch to gold too and fix all regressions in repository including
indirect linking issues.

2. Switch to gold, but add functionality for --copy-dt-needed-entries
which, probably, will never be upstreamed.

3. Do not switch to gold and use semi-supported gnu-ld.
