Making the builds reproducible involves turning off build timestamps,
which some users may find annoying. So make the reproducible builds
optional.

+ help
+ This option will remove all sources of non-reproducibility
+ from the build process. For a given Buildroot configuration,
+ this allows to generate exactly identical binaries from one
+ build to the other, including on different machines.
+
+ This is labeled as an experimental feature, as not all
