rustc computes each crate's Strict Version Hash (SVH) using inputs that include
the *stage0/stage1 bootstrap compiler* fingerprint, which in turn depends on the
build host arch.
This eventually may cause sstate matches across architectures for artifacts that
are actually different, causing autobuilder intermitent reproducibility issues.
To avoid this, pass a fixed value instead of host-specific bits to the specified
hash.

Can you have a look at the issue?
I'll take a look
Thanks,
