Well, capabilities are _always_ compiled into the kernel. The only thing 
changed to enable them are two static data values, specifically the ones 
used to start init with. This happens in one place and one place only. 
Instead of #defines, these could be globals. Of course they would need to 
be set before init is run, so a kernel command line parameter is the only 
place it can be done easily.
Nothing changes thoughout the kernel but these two data values...
