Starting in Go 1.21, the Go toolchain treats a `//go:debug` directive
with an unrecognized GODEBUG setting as an invalid program.
Programs with more than one `//go:debug` line for a given setting
are also treated as invalid.
(Older toolchains ignore `//go:debug` directives entirely.)

You can then replace the existing file with this new downloaded version. 
### Java Toolchain

The Gradle build uses [Java Toolchain](https://docs.gradle.org/current/userguide/toolchains.html) support to compile and execute tests across multiple versions of Java.

# When cross-compiling with RBE, we need to copy the macOS sysroot to be

# target inside "tensorflow/tools/toolchains/cross_compile/cc" so that Bazel
# can register it as an input to compile/link actions and send it to the remote
# VMs when needed.
# TODO(b/316932689): Avoid copying and replace with a local repository rule.
