Rollback of commit bd9f25c593a140acb15d3fd3fc7f66d091e1a898. *** Reason for rollback *** Violates layering - genrule should not depend on platform- or language-specific parts. *** Original change description *** Add a DEVELOPER_DIR make variable to genrules to propagate the apple xcode environment variable DEVELOPER_DIR to commands. If $(DEVELOPER_DIR) is included in the genrule command, we bootstrap the XCODE_VERSION_OVERRIDE environment variable to the command. The contract with the actual action executor is, if XCODE_VERSION_OVERRIDE is present in the environment, to additionally bootstrap the DEVELOPER_DIR absolute path to the command. -- MOS_MIGRATED_REVID=112951074

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.
