It seems the build process tried to create a log file but failed because $HOME is not specified and an assumed home directory is not writable. Note, log files are created under the mozc's config directory.

https://github.com/google/mozc/blob/master/src/base/system_util.cc#L323

Could you please try the following things in your environment?

• comment out LOG(INFO) in gen_collocation_suppression_data_main.cc, and/or
• build with --config=release_build (to set --copt=-DABSL_MIN_LOG_LEVEL=100).
