[GIT PULL] (missing patch) ftrace/kbuild: Add recordmcount filesto force full build

[Steven Rostedt]

Ingo,

This is the missing patch that was suppose to be in tip/perf/core-2 but
was missing due to git mirror lag.

I waited till the git mirrors updated this time.

Please pull the latest tip/perf/core-3 tree, which can be found at:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-2.6-trace.git

    ftrace/kbuild: Add recordmcount files to force full build
    
    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 main dependencies to make sure
    any change to them causes a full recompile.
