[Buildroot] [git commit] uboot: support -b option for mkenvimage

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=bf5487e21e539e474062ee3ace1ac8fb844e38a2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When generating the environment image the target endianess should
be taken in account for CRC calculation purposes. For big endian
targets the -b flag should be passed to the mkenvimage tool.
