I just noticed in the error message I am using ld.bfd for linking currently. Switched to ld.gold and the package links without a problem.
I'm afraid I can't help you here. We really only support USE=libcxxabi these days, the remaining variants are provided for expert users who can handle it.
Alright. As I mentioned, it is now working for me when linking with gold. Maybe the ebuild should enforce using gold with those use flags? Adding a warning message when using unsupported use flags would be a good idea as well.
Well, I'm planning to take a look at all this soon. Most probably, I will lastrite libcxxrt and package.use.force libcxxabi.
