syscall-emul: Ignore unimplemented system calls

Browse source 
This changeset sets the implementation policy for a subset of
system calls to the ignoreFunc implementation (for x86 only).
The ignored system calls likely will never be implemented and
this allows a warning to be issued instead of the simulation
exiting with a fatal.
