ERIKA3 on the Jailhouse hypervisor

Jailhouse is a type-1 hypervisor developed by Siemens and released as Open-Source software.

To build ERIKA Enterprise for Jailhouse, you just need to set the JAILHOUSE_DIR environment variable equal to the directory containing the Jailhouse built objects.

Additionally, in case of cross-compilation, you need to put the cross-compiler in the PATH and set the JAILHOUSE_AARCH64_GCCPREFIX environment variable equal to the cross-compiler prefix.

The build process will create a .bin file that can be loaded through the jailhouse cell load command.
