The error handling when opening config files was ignoring all errors except ENOEXIST. Report other errors, instead of passing nil to json.NewDecoder and getting: config file: out/soong/soong.config did not parse correctly: invalid argument Bug: 73951413 Test: touch out/soong/soong.config && chmod a-r out/soong/soong.config && m Test: rm out/soong/soong.config && m Change-Id: I4a609b7f060b760b76ee829b83c0eb405340f58f
