Pull kbuild updates from Michal Marek: - several cleanups in kbuild - serialize multiple *config targets so that 'make defconfig kvmconfig' works - The cc-ifversion macro got support for an else-branch * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild,gcov: simplify kernel/gcov/Makefile more kbuild: allow cc-ifversion to have the argument for false condition kbuild,gcov: simplify kernel/gcov/Makefile kbuild,gcov: remove unnecessary workaround kbuild: do not add $(call ...) to invoke cc-version or cc-fullversion kbuild: fix cc-ifversion macro kbuild: drop $(version_h) from MRPROPER_FILES kbuild: use mixed-targets when two or more config targets are given kbuild: remove redundant line from bounds.h/asm-offsets.h kbuild: merge bounds.h and asm-offsets.h rules kbuild: Drop support for clean-rule
