Pull Kbuild fixes from Masahiro Yamada:

 - Add proper pahole version dependency to CONFIG_GENDWARFKSYMS to avoid
   module loading errors

 - Fix UAPI header tests for the OpenRISC architecture

 - Add dependency on the libdw package in Debian and RPM packages

 - Disable -Wdefault-const-init-unsafe warnings on Clang

 - Make "make clean ARCH=um" also clean the arch/x86/ directory

 - Revert the use of -fmacro-prefix-map=, which causes issues with
   debugger usability
