`--enable-debug` sets the following CFLAGS, `-g -O0 -DDEBUG`, which
make the built binaries easier to debug using GDB. This doesn't enable
any hidden logging features for debugging.

GlusterFS doesn't dump logs to console. The logs will be dumped to the
relevant log files. For the `gluster` CLI, the log file is
`/var/log/glusterfs/cli.log` for Gluster installed from packages.
To enable debug logs in the log file, use the option
`--log-level=DEBUG` with the CLI command, for eg. `gluster
--log-level=DEBUG volume info`. This works with all GlusterFS builds.
