Use $(info TEXT) func. Like:

uname_s := $(shell uname -s)

$(info Hello to GNU Make build!)
$(info You run at $(uname_s) OS)

Note that $(info) function is in introduced in GNU Make version 3.79 or 3.80
(if I am not wrong).

Current is 3.82. Previous (3.81) released in 2006 and have 'info'.

Also you can use $(shell echo TEXT) but this some ineffective.
