[PATCH v2 04/10] Makefile: print target when debug

[Daniel Gomez <da.gomez@kernel.org>]

From: Daniel Gomez <da.gomez@samsung.com>

When debugging with V=1, print also the Makefile target before the
command.

This allows to speciy the target as well as keep verbosity of the
command being executed. The only limitations is that commands are
printed in one line.

Example:
make V=1
==> [ansible.cfg]
+ ansible-playbook playbooks/ansible_cfg.yml --extra-vars=@./.extra_vars_auto.yaml
[WARNING]: You are running the development version of Ansible. You
should only run Ansible from "devel" if you are modifying the Ansible
engine, or trying out features under development. This is a rapidly
changing source of code and can become unstable at any point.
PLAY 1: ANSIBLE CONFIGURATION ROLE
task 1. [started TASK: Gathering Facts on localhost]
task 2. [started TASK: ansible_cfg : Import optional extra_args file on localhost]
task 3. [started TASK: ansible_cfg : Generate kdevops ansible.cfg on localhost]

==> [inventory]
+ ansible-playbook playbooks/gen_hosts.yml --extra-vars=@./extra_vars.yaml
{...}

Before:
make V=1
[WARNING]: You are running the development version of Ansible. You
should only run Ansible from "devel" if you are modifying the Ansible
engine, or trying out features under development. This is a rapidly
changing source of code and can become unstable at any point.

ansible-playbook  \
        playbooks/gen_hosts.yml \
        --extra-vars=@./extra_vars.yaml
[WARNING]: You are running the development version of Ansible. You
should only run Ansible from "devel" if you are modifying the Ansible
