Description
I'm trying to update the swift-android-action to support building/testing against pre-release snapshots.
Building swift-numerics with 6.1-DEVELOPMENT-SNAPSHOT-2025-03-07-a (grabbed from the artifacts output from https://github.com/finagolfin/swift-android-sdk/actions/runs/13804189225/attempts/1) on ubuntu-24.04 is failing, whereas it works for swift-6.0.3-RELEASE. As seen in the unbutu-24.04 CI build output:
$ /home/runner/swift/toolchains/swift-6.1-DEVELOPMENT-SNAPSHOT-2025-03-07-a/usr/bin/swift build --swift-sdk x86_64-unknown-linux-android24

I'm not sure what the problem might be. Libraries like libswiftCore.so appear to be in the same relative location:

And there are no differences in swift-toolset.json or swift-sdk.json:

It also fails on the macos-13 CI with the same linker errors. But strangely, it does work when building on macOS 15 (both locally and in the macos-15 CI):
zap apple/swift-numerics % ~/Library/Developer/Toolchains/swift-6.1-DEVELOPMENT-SNAPSHOT-2025-03-07-a.xctoolchain/usr/bin/swift build --swift-sdk x86_64-unknown-linux-android24

This repo's build doesn't seem to be using any special flags, and yet all the packages are building for both ubuntu-24.04 and macos-13. What's the difference?
