This is a constant source of confusion and FTBFS, e.g.:
https://buildd.debian.org/status/logs.php?pkg=frr&ver=10.2.1-4

Please remove the Provides: libunwind-dev before trixie.

The Provides+Conflicts: libunwind-x.y-dev is already sufficient to 
ensure that not more than one of the LLVM libunwind-*-dev is installed
at the same time.
