Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild updates from Michal Marek:
"Kbuild changes for v3.16-rc1:
- cross-compilation fix so that cc-option is testing the right
compiler
- Fix for make defconfig all
- Using relative paths to the object and source directory where
possible, plus fixes for the fallout of the change
- several cleanups in the Makefiles and scripts
The powerpc fix is from today, because it was only discovered
recently. The rest has been in linux-next for some time"
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
powerpc: Avoid circular dependency with zImage.%
kbuild: create include/config directory in scripts/kconfig/Makefile
kbuild: do not create include/linux directory
Makefile: Fix unrecognized cross-compiler command line options
kbuild: do not add "selinux" to subdir- twice
um: Fix for relative objtree when generating x86 headers
kbuild: Use relative path when building in a subdir of the source tree
kbuild: Use relative path when building in the source tree
kbuild: Use relative path for $(objtree)
firmware: Use $(quote) in the Makefile
firmware: Simplify directory creation
kbuild: trivial - fix comment block indent
kbuild: trivial - remove trailing spaces
kbuild: support simultaneous "make %config" and "make all"
kbuild: move extra gcc checks to scripts/Makefile.extrawarn
