GLOG currently has trouble with clang-tidy, resulting in clang-diagnostic-error

[hzeller]

With the recent update glog ( #1427 ), clang-tidy seems to have an issue:

bazel-out/k8-fastbuild/bin/external/com_github_google_glog/_virtual_includes/glog/glog/logging.h:458:1: error: expected expression [clang-diagnostic-error]
DECLARE_int32(logbuflevel);
^
bazel-out/k8-fastbuild/bin/external/com_github_google_glog/_virtual_includes/glog/glog/logging.h:411:3: note: expanded from macro 'DECLARE_int32'
  DECLARE_VARIABLE(google::int32, I, name, int32)
  ^
bazel-out/k8-fastbuild/bin/external/com_github_google_glog/_virtual_includes/glog/glog/logging.h:401:12: note: expanded from macro 'DECLARE_VARIABLE'
    extern GLOG_EXPORT type FLAGS_##name;                      \

Let's figure out what the reason is.

CC: @sschaetz Since you added that, can you have a look ?

You can run it locally by calling

.github/bin/run-clang-tidy.sh

This will be fixed with #1448 so probably no action needed now.
