Hello Otavio,

Are there any build/test issues with previous implementation? Can you let me know what are the regression caused by below commits. I want to understand the reason for the changes in this patch.
Fixes: ef566af964 ("rust: fix issue building cross-canadian tools for aarch64 on x86_64")
Fixes: bd36593ba3 ("rust-common: Drop LLVM_TARGET and simplify")
Fixes: 8ed000debb ("rust-common: Fix for target definitions returning 'NoneType' for arm")

Thanks,
Sundeep K.
