Add kernel reduction for embedded as a separate project from user space

as it's a large and somewhat different task.  Flag as soc-friendly.

+      <p>The FreeBSD kernel has been optimized over the years for a
+	server or workstation environment.  Memory is plentiful in these
+	environments, so little attention was given to the size of the
+	kernel.  There's a number items in the kernel that can be made
+	optional without reducing affecting the functionality needed in
+	an embedded environment.  These include things like not
+	compiling in strings into the kernel, less agressively inlining
+	code, making some non-optional features optional and investigating
+	compile time flags.  This task requires identifying potentially
+	optional kernel content and building the infrastructure to make
+	that content optional.</p>
