Initialy yes. But esspecially for cross compiles multiarch dev packages
would be nice. But that will need more developement.

How do you get the libs into /usr/lib/${DEB_HOST_GNU_TYPE} currently? If
your library uses any plugins then you need to compile it for
/usr/lib/${DEB_HOST_GNU_TYPE} and not just move the files there post
build.

Architecture dependent header files belong under
/usr/include/triplet/
That directory is searched by default in gcc so it works without extra
-I option. Preferable to ${libdir}. But dbus screws that up as well as
it uses a subdir for its files.

Would be better but your solution is policy conform too I think.
