Removed host BeOS version recognition: we now always default to target "haiku".

Building our components for use with R5/dano/whatever is now something you need
to want, it's not the default anymore.
Note: you can still build single components for R5 by overriding the target
platform per target, too, for example:
$ TARGET_PLATFORM=r5 jam app_server
