COMPAT_43 is even older than COMPAT_09, so if _43 is enabled, we'll
need everything newer as well.


this isn't traditionally how we did COMPAT_43.  it's more
"enable obsolete interfaces", which is not quite the same
as "make old binaries work".

eg, they enable the old sgtty interfaces that _are_ still
visible and potentially callable from modern binaries.
we still install the headers for this interfaces.

COMPAT_09 enables old binaries with changed interfaces.

i think you should revert this part, untying them.
