#     initramfs: Encode dependency on KBUILD_BUILD_TIMESTAMP
#     
#     gen_initramfs.sh has an internal dependency on KBUILD_BUILD_TIMESTAMP
#     for generating file mtimes that is not exposed to make, so changing
#     KBUILD_BUILD_TIMESTAMP will not trigger a rebuild of the archive.
#     
#     Declare the mtime date as a new parameter to gen_initramfs.sh to encode
#     KBUILD_BUILD_TIMESTAMP in the shell command, thereby making make aware
#     of the dependency.
#     
#     It will rebuild if KBUILD_BUILD_TIMESTAMP changes or is newly set/unset.
#     It will _not_ rebuild if KBUILD_BUILD_TIMESTAMP is unset before and
#     after. This should be fine for anyone who doesn't care about setting
#     specific build times in the first place.
