#     kbuild: mkcompile_h: consider timestamp if KBUILD_BUILD_TIMESTAMP is set
#     
#     To avoid unnecessary recompilations, mkcompile_h does not regenerate
#     compile.h if just the timestamp changed.
#     Though, if KBUILD_BUILD_TIMESTAMP is set, an explicit timestamp for the
#     build was requested, in which case we should not ignore it.
#     
#     If a user follows the documentation for reproducible builds [1] and
#     defines KBUILD_BUILD_TIMESTAMP as the git commit timestamp, a clean
#     build will have the correct timestamp. A subsequent cherry-pick (or
#     amend) changes the commit timestamp and if an incremental build is done
#     with a different KBUILD_BUILD_TIMESTAMP now, that new value is not taken
#     into consideration. But it should for reproducibility.
#     
#     Hence, whenever KBUILD_BUILD_TIMESTAMP is explicitly set, do not ignore
#     UTS_VERSION when making a decision about whether the regenerated version
#     of compile.h should be moved into place.
