The previous changes cause sstatetests.SStateTests.test_sstate_32_64_same_hash to fail since RUST_XXX_SYS changes depending on the native architecture. This is correct but these are accounted for in the layout of paths in TMPDIR so they should be excluded from the task signatures for the correct behaviour.
