Adding feature for cross-compilation hbosng

[LarsGrootkarzijn]

• Added --arch variable to sbuild. The value for this is given as a parameter.

For example:

build.sh arm64

This will however most likely introduce a lot of redundant code; Sanity architecture check in build-all -> Sanity architecture check in build.sh acr folder hbosng -> sanity architecture check in build.sh acr repository.

Technically, you can run each build.sh separately which means these checks are necessary. While when running build-all the sanity check is conducted immediately, and does not have to be conducted in the build.sh script(s).

build.sh should be able to compile without any argument.
The --arch should only be applied when the user explicitely wants to build for a specific architecture. This is optional.

The best way to check is to add --arch xxx as a command line argument to build.sh, parse it and add it only when given

Hi, Yes, I fully agree, this should have been a draft, I improved this yesterday night, will push in a bit.

Hi @hifiberry, I changed the script, let me know what you think of this structure, so I can start working out the others. Currently, arch is standard at arm64. I could change this to the target architecture being the same as the host machine, but I think in most cases arm64 is goto.

Looks good now

I think arm64 as default is fine
