Please feel free to disregard my feedback if it's not applicable. Should the Dockerfile be update to FROM alpine:3.21 based on your comment regarding loongarch64 support in Alpine Linux?

[wojiushixiaobai]

OK, let me correct it.

[rvagg]

Can you tell me what this is trying to do? these builds normally only happen on x64 and we only get a single, stable arch build out of these to publish to unofficial-builds.nodejs.org. We have separate loong64 and riscc64 recipes to handle those cases.

Or are you trying to use this to do local builds for musl on these architectures?

[wojiushixiaobai]

This change allows you to directly run scripts on physical machines of other architectures to build.
This way we don't need to add files for other architectures, such as #157
