[RFC][PATCH 2/2] ftrace/kbuild: Add recordmcount files to force full build

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

Modifications to recordmcount must be performed on all object
files to stay consistent with what the kernel code may expect.
Add the recordmcount files to the force-deps to make sure
any change to them causes a full recompile.
