commit 7e5619a6abe7ce89eb55b411736025b31410f478

    Fix `make clean` for `real/compress`
    
    Summary:
    The `make boot` phase of `real/compress` generates files that are
    cleaned up by `make clean` with `rm`. Doing `make clean` without a
    prior `make boot` leads to a failure.
    
    This just supplies `-f` to `rm` so that plain `make clean` no longer
    fails.
