72d0facc37
1. Rewrote hipcc_cc_toolchain_config.bzl.tpl.oss based on third_party/bazel/tools/cpp/unix_cc_toolchain_config.bzl 2. Cleaned up non-Linux stuff in toolchain configuration 3. Added support for parameter file in the compiler wrapper script 4. Re-generated preconfigured toolchain by third_party/tensorflow/third_party/toolchains/preconfig/generate/update.sh ubuntu16.04-py3_opt-gcc5-rocm 5. Bumped min Bazel version to 0.27.1 because toolchain configure requires newer Bazel 6. Removed --noincompatible_do_not_split_linking_cmdline PiperOrigin-RevId: 278844463 Change-Id: I477ec5b44e6c634db7c6d65d02b3e307f0be338b
