Phobos static lib not build properly anymore after update to binutils 2.30 on NixOS

[Thomas Mader <thomas dot mader at gmail dot com>]

Hello,

I need a little support to figure out a problem on NixOS with binutils.
You will find detailed information here:
https://github.com/NixOS/nixpkgs/issues/40397

I don't think it's binutils bug because it works on Archlinux with binutils
2.30. Though they use one newer version of dmd/phobos but that should not
matter as the Changelog doesn't mention any fixes regarding binutils and
the build on NixOS also works with the same dmd/phobos version but binutils
2.28.1.

But somewhere is a bug and I am having a hard time figuring out in which
direction to go from here or to narrow down the problem. So I thought I try
to contact the binutils mailing list for help.

Thanks in advance
Thomas
