@alexfmpe:matrix.orgalexfmpebisect was pretty quick: this broke eval: https://github.com/NixOS/nixpkgs/pull/36659317:39:01
@alexfmpe:matrix.orgalexfmpe somehow we're getting a
ghcjs -> emscripten -> openjdk -> python -> openssl
that ends up trying to eval stdenv.cc.isGnu that then throws because there's no c compiler
