[Buildroot] [PATCH v3 2/2] powerpc-utils: optionally use librtas

[Romain Naour <romain.naour@openwide.fr>]

> Now that librtas is available, optionally use it with powerpc-utils to
> enable it's RTAS dependant functionality.  It is used by default, as
> most distros do, but made optional because it adds several new programs
> and significantly increases the size of the installed package.

The librtas reverse dependencies should be added here (glibc toolchain only and
!static build)
