We build both flang and flang-rt. We install later via `cmake --install`, a full build log can be found [here](https://download.copr.fedorainfracloud.org/results/@fedora-llvm-team/llvm-snapshots-big-merge-20260601/fedora-rawhide-x86_64/10529854-llvm/builder-live.log.gz).

Reading that, it does install these files:

so the location changed? Is _that_ on purpose?
