make_isa_stub and hardlines

[sjorge]

Hey make_isa_stub does not detect hardlinks, maybe it should to save on package size.

Example Manifest that is generated:
http://omnios.blackdot.be/manifest/0/obd%2Farchiver%2Fpar2cmdline%400.4%2C5.11-0.151006%3A20130716T133242Z

As you can see the make install creates some hardlinks for par2. make_isa_stub creates small stubs for them too, everything works as expected however a hardlink to the stub of par2 would work just as well.

I think this would be a nice feature to have, depending on the amount of work it would be to implement. If it is a whole lot of work, it's probably not worth the effort.
