Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
Pull kbuild updates from Michal Marek: "Just a few kbuild core commits this time: - kallsyms fix for CONFIG_XIP_KERNEL - bashisms in scripts/link-vmlinux.sh fixed - workaround to make DEBUG_INFO_REDUCED more useful yet still space efficient - clang is not wrongly detected when cross-compiling" * 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: kbuild: include core debug info when DEBUG_INFO_REDUCED scripts: link-vmlinux: Don't pass page offset to kallsyms if XIP Kernel scripts: fix link-vmlinux.sh bash-ism Makefile: Fix detection of clang when cross-compiling
