Looking at your kbuild branch, I see subsequent changes that require 
minor adjustments. Please merge the following patch:

Subject: [PATCH] kbuild: adjust ksym_dep_filter for some cmd renames

The following renames occurred recently:

  cmd_cc_i_c --> cmd_cpp_i_c
  cmd_as_s_S --> cmd_cpp_s_S

The respective cc_*_c and as_*_S patterns no longer match the above
therefore additional patterns are needed.
