Update XLA to latest upstream revision. Major rework of the Nix packaging to handle rules_python's hermetic Python toolchain, which downloads a pre-built CPython binary that requires patchelf in the Nix sandbox. Key changes: - Patch rules_python to patchelf the hermetic Python binary using NIX_DYNAMIC_LINKER from --repo_env - Normalize /nix/store paths in the deps archive for reproducibility - Remove non-deterministic .pyc files from deps - Fix #!/usr/bin/env shebangs in rules_python for the Nix sandbox - Drop aarch64-darwin and aarch64-linux platforms (blocked by upstream oneDNN bug: https://github.com/openxla/xla/issues/38673)

Patch rules_python to run patchelf on the downloaded hermetic Python binary.
|
|
Pre-built binaries reference /lib64/ld-linux-x86-64.so.2 which doesn't exist
|
|
in the nix sandbox. Use patchelf to set the correct dynamic linker.
|
|
|
|
This patch is added to the rules_python download in python_init_rules.bzl
|
|
and applied after rules_python is fetched.
