The 11.0.0-alpha.1.26065.101 version of the microsoft.netcore.app.runtime.nativeaot.ios-arm64 pack (and probably other packs for other RIDs as well, I haven't checked) are missing the following files:

• libSystem.Globalization.Native.a
• libSystem.IO.Compression.Native.a
• libSystem.Native.a
• libbrotlicommon.a
• libbrotlidec.a
• libbrotlienc.a

They were present in 11.0.0-alpha.1.26062.101

This started happening in this maestro PR: dotnet/macios#24508

specifically this commit: dotnet/macios@ee15359

I tried looking through the relevant dotnet/runtime commits, but I didn't see anything obvious causing this.
