[Buildroot] [PATCH] uboot: support -r option for mkenvimage

From: Simon Dawson <spdawson at gmail.com>

Some boards are configured in u-boot to store multiple redundant copies of
the environment image in flash. For these boards, it is required to pass the -r
flag, when generating a boot environment image using mkenvimage.
