This will let us add big endian testing to CI for our C code. (We were already doing it for our Rust code.) This is adapted from test_vectors/cross_test.sh. It works around the limitation that the `cross` tool can't reach parent directories. It's an unfortunate hack, but at least it's only for testing. It might've been less hacky to use symlinks for this somehow, but I worry that would break things on Windows, and I don't want to have to add workarounds for my workarounds.

# This hacky script works around the fact that `cross test` does not support
|
|
# path dependencies. (It uses a docker shared folder to let the guest access
|
|
# project files, so parent directories aren't available.) Solve this problem by
|
|
# copying the entire project to a temp dir and rearranging paths to put "c" and
|
|
# "reference_impl" underneath "blake3_c_rust_bindings", so that everything is
|
|
# accessible. Hopefully this will just run on CI forever and no one will ever
|
|
# read this and discover my deep shame.
