It is result of unification. waf 2.0 has now 'top' and 'out' to point to
source and binary build directories. We also use 'top' to find out where
buildtools are, so end result is that out is defined as $top/bin.

It seems to play well with lib/* libraries.

I'll look what could be done to preserve this use case.
