This builds i386 and then later x86_64 (and other ARCH values) in the same source/output tree. Kbuild is not reliable when reusing the same output directory across different defconfigs/bitness/architectures; stale objects can lead to flaky failures or false passes. Use per-config out-of-tree build dirs (e.g., via O=/KBUILD_OUTPUT) or run a clean step (e.g., make mrproper) between architecture/bitness switches.

The clang i386 build reuses the artifacts from the preceding GCC i386 build in the same directory. Even if many objects rebuild, this can still mask clang-only build issues or cause confusing incremental-build behavior. Consider using a separate O= output dir for the clang pass (or cleaning before the clang build) so it is a true from-scratch clang build for this config.
