Fix NPE in Android{S,N}dkRepositoryFunction.

If neither the path attribute or the $ANDROID_HOME/$ANDROID_NDK_HOME environment
variable is set, we should report a helpful error message. A previous change
switched the lookup for the environment variable from the client environment map
to the skyframe environment map. However in the skyframe action environment map,
environment variables that are requested but not set in the environment have
null values.

Followup to change needed for #2621.

Bazel (Beta)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
