[xMach-core] call for proposals

[janb]

We are heby requesting proposals on the issue of binary formats for xMach.
The obvious ones are ELF and a.out. Less obvious would be mach-o for fat
binary capability, since we eventually want to get this baby on different
architectures.
If you have suggestions and comments, please submit them. This is for the
mid-term, probably post 1.0, but we need to get the discussion going
already.
