Defining android_ndk_repository() will prevent non-Android targets from building if ANDROID_NDK_HOME is unset

Seems like #2722 is somehow back in bazel v5.0.0.
Was not happening for me on bazel v4.x.x.

In a macro file included from my WORKSPACE I have the following defines (without loss of generality):

native.android_sdk_repository(
    name = "androidsdk",
    api_level = 28,
    build_tools_version = "30.0.3",
)

native.android_ndk_repository(
    name = "androidndk",
    api_level = 29,
)

No special flags on the command line (no extra_toolchains, crosstool_top, cpu or such).

And yet, the outcome is build failing:

bazel build -s my-target
ERROR:WORKSPACE:37:8: fetching android_ndk_repository rule //external:androidndk: Either the path attribute of android_ndk_repository or the ANDROID_NDK_HOME environment variable must be set.
ERROR: Analysis of target '//my-target' failed; build aborted: Either the path attribute of android_ndk_repository or the ANDROID_NDK_HOME environment variable must be set.
