Pull kbuild fixes from Michal Marek:
 "There are two more kbuild fixes for 3.6.

  One fixes a race between x86's archscripts target and the rule
  (re)building scripts/basic/fixdep.  The second is a fix for the
  previous attempt at fixing make firmware_install with make 3.82.
  This new solution should work with any version of GNU make"
