Cross-compiling Bazel for arm64 platforms is broken #15465
Description
Description of the bug:
During our release process, we encountered the following errors when cross-compiling for macOS arm64 and Windows arm64 platforms
ERROR: /Users/buildkite/builds/bk-trusted-macpro-4/bazel-trusted/bazel-release/src/BUILD:166:10: Illegal ambiguous match on configurable attribute "srcs" in //src:embedded_jdk_minimal_cached:
//src/conditions:darwin_x86_64
//src/conditions:darwin_arm64
Multiple matches are not allowed unless one is unambiguously more specialized.
ERROR: C:/b/bk-trusted-windows-qkvt/bazel-trusted/bazel-release/src/BUILD:166:10: Illegal ambiguous match on configurable attribute "srcs" in //src:embedded_jdk_minimal_cached:

//src/conditions:windows_x86_64
What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.
On macOS x86_64:
export USE_BAZEL_VERSION=108c17859c255a350724b661b74e19aeacf44fe6
bazelisk build --nobuild --cpu=darwin_arm64 //src:bazel
On Windows x86_64:
export USE_BAZEL_VERSION=108c17859c255a350724b661b74e19aeacf44fe6
bazelisk build --nobuild --cpu= x64_arm64_windows //src:bazel
