boost: disable on NIOS 2 with broken toolchains

The current NIOS 2 toolchains are not capable of building Boost, so
let's disable it and its reverse dependencies. Even though it's not
strictly an architecture dependency, we use the <pkg>_ARCH_SUPPORTS
paradigm for this dependency, since it simplifies a lot handling all
boost reverse dependencies, and is anyway quite similar to an
architecture dependency since we don't display a comment about this
dependency.

Fixes:
