kernel: predefine KBUILD_BUILD_USER and KBUILD_BUILD_HOST
By exporting KBUILD_BUILD_USER with a pre-defined value we improve the reproducibility of the kernel and remove the requirement for whoami in the HOSTTOOLS. KBUILD_BUILD_HOST also helps improve the reproducibility of the kernel. For more kernel reproducibility options see: https://lwn.net/Articles/437864/ (From OE-Core rev: a5a14edb5573e33667b63b1e34cb4e19d075e8e8) Signed-off-by: Joshua Lock <joshua.g.lock@intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
