Bootstrapping: don't use convenience symlinks When `compile.sh` builds bazel using bazel, it copies the resulting binary to `output/bazel`. However sometimes the convenience symlink `bazel-bin` is not created, probably because an old one is still around and cannot be deleted. That is clearly a bug, but to work around it, the bootstrap builder shouldn't attempt to rely on the creation of these symlinks in the first place. This change updates compile.sh to use `bazel info` to locate the `bazel-bin` directory's real path, and attempt to copy the bazel binary from there. This works around https://github.com/bazelbuild/bazel/issues/1827 -- MOS_MIGRATED_REVID=134398451
{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.
