Here's my build command:
swift build --product API -c release --static-swift-stdlib -Xlinker -L/usr/lib64 -Xlinker -lc++
That was the result of ChatGPT's guidance. But I also tried these:
swift build --product API -c release --static-swift-stdlib
swift build --product API -c release --static-swift-stdlib -Xlinker -lc++
swift build --product API -c release --static-swift-stdlib -Xlinker -L/usr/lib64
Here's the output of the top command:

/usr/lib64/libstdc++.so.6
So it appears to me that the libstdc++ is present on my Amazon Linux 2 instance. But apparently it's not capable of being found during linking. I've faced a building issue with Docker in the past on a Intel Mac and the issue was with running out of memory while building. I increased the ram of the Docker instance and everything started working properly. In this case I'm on an AWS EC2 instance with 16GB of ram, so I don't think that's the problem this time around.
Here's the output of specifying the library directly with the -v parameter:
swift build --product API -c release --static-swift-stdlib -Xlinker -L/usr/lib64 -Xlinker /usr/lib64/libstdc++.so.6.0.24 -v
