During the build, Ruby has special logic to serialize its own builtin module to disk using the binary iseq format during the build (I assume for speed so it doesn't have to parse builtin every time it starts up). However, since iseq format is architecture-specific, when building on x86_64 for universal x86_64 + arm64, the serialized builtin module is written with the x86_64 architecture of the build machine, which fails this check whenever ruby imports the builtin module on arm64:1fdaa06660/compile.c (L13243)Thankfully, there's logic to disable this feature for cross-compiled builds:1fdaa06660/builtin.c (L6)This disables the iseq logic for universal builds as well. Fixes [Bug #18286]
