Build failure on Mariner (azurelinux) because of unsupported cipher chacha20_poly1305

[GalBr]

When trying to build cryptography from source on Mariner (azurelinux), the build fails:

  error[E0599]: no function or associated item named `chacha20_poly1305` found for struct `openssl::cipher::Cipher` in the current scope
     --> src/backend/aead.rs:459:50
      |
  459 |                         openssl::cipher::Cipher::chacha20_poly1305(),
      |                                                  ^^^^^^^^^^^^^^^^^ function or associated item not found in `Cipher`

Apparently Mariner doesn't support chaha20_poly1305. It seems that Azure patched the problematic code in order to work around this issue. (source)
The package was installed with pip install --no-binary ":all:".
Is this a known issue? Are there plans to integrate something more robust to the build? Some way to avoid this issue aside from changing the source code or using a wheel?

Is the OpenSSL that mariner has built with OPENSSL_NO_CHACHA? We don't currently support that build configuration, but we'd accept a patch to build correctly with it.
