rpm-sequoia is Rust based.

rust[-native] in Yocto master depends on llvm[-native].

The target build just uses the shlib dependencies (only libssl.so.3,
libcrypto.so.3, libgcc_s.so.1, and the C runtime), but the native build
pulls in the whole destdir for each build dependency.

So, it's not actually true that none of the build dependencies
are needed, but the openssl libs and the libgcc_s native builds
are pulled in via some other recipes that are needed in native sysroots.

Anyway, noth rust-native and llvm-native are quite heavy, so
not copying them speeds up packaging a little and saves disk space.

llvm-native also conflicts with clangXX-native builds in meta-clang-revival.

Recipes using TOOLCHAIN = "clang14" or similar build successfully,
but extend_recipe_sysroot in staging.bbclass fails when re-run
before packaging.

See my previous mail at
https://lists.openembedded.org/g/openembedded-core/message/225411

Currently this change is in the layer.conf of meta-clang-revival,
but the speedup and the disk space saving worth it to have
it in oe-core.

I will send v2 with the extended explanation and only omitting
rust-native and llvm-native.
