That's a great feature for porting. No compiler changes, ....

Any comments to this from ETH, Pieter, Patrik ?
In the end my question is:
Is it possible to use the LNO strategy also for a Linux Bluebottle ?
Which means:
- Taking a running Bluebottle on a machine where there is also a Linux.
- Create a Linux version of a "statically linked inner core of Bluebottle".
- Convert it to ELF with the existing ElfLinker.Mod
- And we are done :-)

So I would go for the binary compatibility for now if possible.
