In the issue below, it was reached a consensus that BOLT [can reject such cases](https://github.com/llvm/llvm-project/issues/100096#issuecomment-2253322315), therefore I am closing this PR.

I rebased it (as it was a stacked PR) and added some comments in case someone has such a binary and needs a workaround or a starting point.
