Due to other changes in the kbuild tree, I suspect. However, as you say,
this part is not relevant to the warning I am getting.

Also see my other email. For a i386 defconfig build, I get this warning
only twice, for a sparc64 defconfig I get 4 and for a sparc32 defconfig,
none:
At top level:
cc1: warning: unrecognized command line option "-Wno-unused-but-set-variable"
