Subject: [PATCH 20/39] gcc 4.8+ won't build with --disable-dependency-tracking

since the *.Ppo files don't get created unless --enable-dependency-tracking is true.

This patch ensures we only use those compiler options when its enabled.

Upstream-Status: Submitted

(Problem was already reported upstream, attached this patch there
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55930)
