Issue Description:

<unknown>:0: error: symbol '$s13PluginManagerAAC8withPath15pluginExtension11loadPluginsAByxG13SystemPackage04FileD0V_SSSgSbtYaKcfcTu' (async function pointer to PluginManager.PluginManager.init(withPath: SystemPackage.FilePath, pluginExtension: Swift.Optional<Swift.String>, loadPlugins: Swift.Bool) async throws -> PluginManager.PluginManager<A>) is in generated IR file, but not in TBD file
<unknown>:0: error: please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the project, and add '-Xfrontend -validate-tbd-against-ir=none' to squash the errors

This is on aarch64, using futurejones pre-built swift package installed using apt, running on a VM on a MacbookPro M1 Max using the UTM VM runtime. Basically, the arm-native VM/OS/toolchain combo readily available.

The attached projects build and run the unit test suite fine on macOS 12.1 with the toolchain:

jocke@max ~> swift --version
swift-driver version: 1.26.21 Apple Swift version 5.5.2 (swiftlang-1300.0.47.5 clang-1300.0.29.30)
Target: arm64-apple-macosx12.0
jocke@max ~>  

But falls over on the linux VM.

To reproduce, just install the attached project on an arm-ubuntu and try to run with the 5.5.2 toolchain from futurejones.

Adding this to the target helps the build go through and the project works:

swiftSettings: [
  .unsafeFlags(["-Xfrontend", "-validate-tbd-against-ir=none"]) // due to https://bugs.swift.org/browse/SR-15629
] 

[swift-ci]

Comment by ChecqChe (JIRA)

yes

Forgot I had a local package there also - added swift-plugin.tar.gz that needs to be a peer directory to swift-plugin-manager for building.

This is fixed with toolchain:

ubuntu@linux:~/GitHub/SR-15629/swift-plugin-manager$ swift --version
Swift version 5.7.1 (swift-5.7.1-RELEASE)
Target: aarch64-unknown-linux-gnu
