Subject: [BUILD] Fixup support for building upstream kernels.

In particular:
 - support merged x86 architecture. To facilitate this it made sense
   to encode some existing logic in shell scripts rather than
   increasing complicated make conditionals.
 - set CONFIG_PARAVIRT_GUEST=y which is required for newer kernels.
