Enabling this significanly reduces the size of llvm-rust to about a third
of what it was, which is a bettter configuration for us leading to smaller
TMPDIR and sstate objects

It will slow down the compiler execution and sometimes its could be significant as well we have seen this with clang so it would be good to have some idea around that least we provide a slow compiler compared to other distro infrastructures


We'll get some performance info from the YP AB perf builds.

Sundeep,

Once we see if there's a noticeable difference in those YP AB runs,
we should  look into bench-marking  the build time for ru= st and
check for any difference in building Rust  in the SDK and mayb= e even on target as another benchmark.

This is less urgent than getting the failing and skipped rust tests enabled but it shouldn't wait too long.
