From b169f6a9a1091224899e7d1872dfdd99b38e349e Mon Sep 17 00:00:00 2001

Subject: [PATCH] Make:Use "simply expanded" make variables.

Replace some "recursively expanded" make variables with "simply
expanded" variables (i.e. replace = with :=). This has no functional
impact but is more consistent and theoretically more efficient.
