We need full target passed for build so we changed the
rust-cross-canadian to use same code used in regular rust recipes and
added support to use specific llvm-target for the building host.
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")
