-Subject: [PATCH 07/10] Allow overriding crate_hash with -C crate_hash
-
-The current crate hash is not stable from run-to-run.  This causes
-problems with bitbake; it needs a guarantee that every build with the
-same input will generate compatible output, otherwise sstate won't work.
-Using -C crate_hash, we can do that by using the bitbake input hash to
-determine the crate hash; the bitbake input hash will be stable, but
-still different for different rust recipes.
-
-Upstream-Status: not-appropriate
-
-Upstream wants to fix it's actual object generation here. See
-https://github.com/rust-lang/rust/issues/34902 (and others) for details.

+When using a native llvm-config from inside a sysroot, we need llvm-config to

+llvm-config from a target sysroot.
