Hm... you have a strange dichotomy between wanting make to be a "black
box" etc. on one hand, and wanting the makefiles to be "more readable"
on the other hand :).

More efficient.

ls itself has a lot more overhead than wildcard, because not only is ls
a separate process but it does a lot more than just return the names of
files.  If you don't bother with the formatting you can do the whole
thing in one shell (plus a /bin/echo if it's not builtin to your shell)
if you use wildcard, rather than two shells, at least 6 echos, 2 ls's
and 2 xargs; that's 2 process invocations vs. 12 :).
