If it is treated as a user error than a warning should be printed because this
changes the behavior of what is dropped and what is not. People

It seems that it works with -fno-use-linker-plugin - strane :S
Now I will try to check some other things.
I think it is not a linker bug

-fno-use-linker-plugin is used. When linker plugin is used gcc drops these
sections.
