https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-embedded/libmpsse misses USE=static-libs and installs '.a' files. Discovered on: amd64 (internal ref: booboo_tinderbox) The best solution is avoid to build the '.a' files by touching the configure. In case the buildsystem makes your life hard, a good compromise would be just remove the files.
