Initialize subdir-rustflags-y to an empty value to prevent it from being
inadvertently affected by an environment variable of the same name.

Applied to kbuild/linux.git (kbuild-next-unstable), thanks!

[1/1] kbuild: set the initial value of subdir-rustflags-y
      https://git.kernel.org/kbuild/c/2c5a2273

Please look out for regression or issue reports or other follow up
comments, as they may result in the patch/series getting dropped,
reverted or modified (e.g. trailers).

Patches applied to the kbuild-next-unstable branch are accepted pending
wider testing in linux-next and any post-commit review; they will
generally be moved to the kbuild-next branch in about a week if no
issues are found.

Best regards,

Sounds good, thanks!

I guess we can take this via either Kbuild or Rust -- happy either way.

Cheers,
