[XEN PATCH v1 2/4] automation: add cross-compiler support for the build script

[Oleksii Kurochko <oleksii.kurochko@gmail.com>]

Docker images that are currently available and used for
cross-compilation is additionally installed GCC/Binutils
which is why the build script doesn't crash.

RISC-V docker image doesn't have native GCC only          
cross-compiler which will lead to the fact  that the build
script will fail.
