Glauber's old Accel interface was close to the right approach.  We need 
to abstract the exec.c interfaces to use a function pointer table and 
have a TCG and KVM implementation.  The function pointer tables can then 
be registered by a module_init() and we can simply not include the kvm 
or TCG files are build time to disable the functionality.
