This is needed to build boost asio as a shared library rather than a
header-only library, which is needed to save memory.

Why specifically asio and nothing else? If we want to build bits of
boost as shared libraries where upstream only supports them as
header-only libs, then there should be a general solution, and ideally
one that is accepted upstream.

I think you need to discuss with boost upstream first before proposing
something custom for core.
