OpenSSL "pc" file missing

I ran:

docker run swift:5.5-amazonlinux2 /bin/bash -c "swift --version"

And the output was:

Swift version 5.5.3 (swift-5.5.3-RELEASE)
Target: x86_64-unknown-linux-gnu

I also tried explicitly executing the Docker packaging command using a Swift 5.5.3 image:

docker run \
        --rm \
        --volume "$(pwd)/:/src" \
        --workdir "/src/" \
        swift:5.5.3-amazonlinux2 \
        /bin/bash -c "swift build --product API -c release --static-swift-stdlib"

But got the same error (linking error).

Also, I've since removed Kitura's SwiftJWT completely — replacing it with Vapor's JWTKit — but the linking error persists.
