# Bazel sets '-B/usr/bin' flag to workaround build errors on RHEL (see
# https://github.com/bazelbuild/bazel/issues/760).
# However, this stops our custom clang toolchain from picking the provided
# LLD linker, so we're only adding '-B/usr/bin' when using non-downloaded
# toolchain.
# TODO: when bazel stops adding '-B/usr/bin' by default, remove this
# flag from the CROSSTOOL completely (see
# https://github.com/bazelbuild/bazel/issues/5634)
