Just looked for the reasons, which appear to be there:
commit 39c015c556f285106931e0500f301de462b0e46e

    Fixes for ancient versions of GNU make

    Some versions of GNU make do not understand $(call), and have problems to
    interpret rules like this:

    some_target: CFLAGS += -Dsome=defs

    [jc: simplified substitution a bit. ]

I trust Johannes to have such a make, never seen it myself, though.

Race condition. Hit the send button before reading his patch and
the related discussion. Besides, now I find it is already too much
cruft just to print a directory. Didn't want to make it pretty, just
needed some readability on screen. Still think the errors of
(eventually) failing install would be enough.

Using $(call) would allow to generalize that, BTW.
