Building the Mender client for arm64

[Arnstein Kleven]

Just a heads up for anyone trying to build the Mender client for arm64:

When running "GOARCH=arm64 go build ." I got "no buildable Go source files in /home/arnstein/go/src/github.com/mendersoftware/mender/vendor/github.com/bmatsuo/lmdb-go/lmdb". With some help from the Mender team I was able to build the client for arm64 with the command:

CC=aarch64-linux-gnu-gcc CGO_ENABLED=1 GOARCH=arm64 go build .

I should add that when you run this, it will give this error:

./ioctl.go:40: undefined: UBI_IOCVOLUP

./ioctl.go:121: undefined: BLKSSZGET

./ioctl.go:142: undefined: BLKGETSIZE64

By copying these variables from ioctl_64_bit.go into ioctl.go (or much better: properly importing this file into the project), it will work.

Does the attached patch work?

Yes, after removing the constants that I added to ioctl.go and applying the patch I can confirm that this works.

Cool, I'll make sure that gets submitted to the repo.
