I.e. the IP address 127.0.0.1.

I think you just need to change /etc/hosts so that 'hostname' returns 
a name whose first IPv4 address is 127.0.0.1.

Alternatively, just write a tiny object file to implement your 
gethostid() function, returning whatever you want, and LD_PRELOAD it 
when running your application.
