Bug#1075931: llvm-toolchain-18: Broken symbolic links in llvm packages

[liuxiangyu]

Source: llvm-toolchain-18
Version: 1:18.1.8-2~exp2
Severity: important
X-Debbugs-Cc: u122334 at gmail.com

Dear Maintainer,

Some of broken symbolic links are found in full installation of llvm-toolchain-18, in a sid + experimental schroot for amd64.

(In sid + experimental schroot for x86_64)
# apt-get -V -t experimental --auto-remove --purge --no-install-recommends install bolt-18 clang-18 clang-18-doc clang-18-examples clangd-18 clang-format-18 clang-tidy-18 clang-tools-18 flang-18 libbolt-18-dev libc++1-18 libc++-18-dev libc++-18-dev-wasm32 libc++abi1-18 libc++abi-18-dev libc++abi-18-dev-wasm32 libclang1-18 libclang-18-dev libclang-common-18-dev libclang-cpp18 libclang-cpp18-dev libclang-rt-18-dev libclang-rt-18-dev-wasm32 libclang-rt-18-dev-wasm64 libclc-18 libclc-18-dev libflang-18-dev libfuzzer-18-dev liblld-18 liblld-18-dev liblldb-18 liblldb-18-dev libllvm18 libllvm-18-ocaml-dev libllvmlibc-18-dev libmlir-18 libmlir-18-dev libomp-18-dev libomp-18-doc libomp5-18 libpolly-18-dev libunwind-18 libunwind-18-dev lld-18 lldb-18 llvm-18 llvm-18-dev llvm-18-doc llvm-18-examples llvm-18-linker-tools llvm-18-runtime llvm-18-tools mlir-18-tools python3-clang-18 python3-lldb-18

Seems that the links in libc++abi-X.Y-dev.links.in, libc++-X.Y-dev.links.in and python3-lldb-X.Y.links.in are not pointing to the correct targets after closing #1067699, #1067005.

There should be some updates for links.in files above.
