Because that's how it's documented to work. See "The '--print
-directory' Option" in the GNU make manual:
Normally, you do not need to specify this option because ‘make’ does
it for you: ‘-w’ is turned on automatically when you use the ‘-C’
option, and in sub-makes. make will not automatically turn on ‘-w’
if you also use ‘-s’, which says to be silent, or if you use
‘--no-print-directory’ to explicitly disable it.
