.if and .for are unrolled and evaluated while parsing the makefile
and make transforms it to bare "@${ECHO_MSG} ..." lines with the
content that depends on the if-else-endif evaluation.  LOCALBASE
isn't defined at that time

And targets are executed after the whole Makefile was read, so
LOCALBASE is here.  Actually, the found "/usr/local/etc/rc.d/motd"
is really an "/etc/rc.d/motd".
