pullrequest feat

Hello everyone, my name is Nico, and I’m from China. I’m a senior IT
systems architect, and I use Make in my daily work to build IT environments.

In my scripts, I have a lot of code like the following to print logs:
define loginfo =
@echo "$$(date -d today +'%Y-%m-%d %T') info:  [$(@)]-$(1)"
endef
I wish Make had native support for this functionality
$(info some message)
so I made some minor modifications to implement it. Now, I’d like to merge
these changes into the main branch.
