As we already discussed, sl/dl/hl have the problem that when a
non-header-only library links to a header-only one which in turn links to a
non-header-only one, the sl/dl of the first one should propagate to the
third, which is problematic if the second has to be -hl.

The way this works in Boost.Build is that the user indeed writes the
equivalent of the above, and then the link=static property is propagated to
the dependencies.

If there's a library that has an optional header-only mode, this is not
encoded as link=header, but as define=BOOST_BAR_HEADER_ONLY.

That is, when you have foo depending on bar depending on baz, the
link=static;define=BOOST_BAR_HEADER_ONLY property set is propagated from foo
to bar to baz and everything works more or less as expected.
