Hi Baruch,

I thought about making it optional, but there seemed to be two reasons
to always include it:

* librtas is a small library and it provides a lot of functionality to
powerpc-utils. Why leave it out?

* Distros (AFAIK) always include librtas when providing powerpc-utils,
so it would surprise users to provide a powerpc-utils without it by
default. So if I did make it optional, I think it should be using some
method that caused librtas to be included by default or at least
provided some indication in the menu that they may want to go and enable
librtas. Then I thought this was a bit complicated for a use case that I
couldn't find a reason for.

That said, if you have a reason to make it optional I'll be happy to
make it so. Maybe using a sub-option to add the dependency, and that
could default to yes?

e.g.

[*] powerpc-utils
	[*] RTAS functionality

Cheers,
Sam.
