[Buildroot] [PATCH v2 07/15] reproducibility/busybox: disable build timestamps

[Jérôme Pouiller]

From: Gilles Chanteperdrix <gilles.chanteperdrix at xenomai.org>

Busybox include a few information about build environment in its binary. This
feature is incompatible with BR2_REPRODUCIBLE feature. This patch overload build
information when BR2_REPRODUCIBLE is enabled.
