On Debian and its derivatives (unlike other Linux distributions) the
compiler's default search path includes /usr/include/${DEB_HOST_MULTIARCH},
so it is possible to have headers that are available by default
*and* in an architecture-specific location.
The most appropriate place depends whether the intended API for libzip-dev is
"you should be able to use this library with cc -lzip" or "you are
expected to use pkg-config", which is partially a question for upstream.
GLib and libdbus are among the libraries whose intended API is "you are
expected to use pkg-config". Their headers are very deliberately not
on the compiler's default search path, and you are expected to put
something like `pkg-config --cflags glib-2.0` on the compiler command-line.
However, if libzip was in that category, I would expect it not to install
zip.h in the compiler's default search path. Getting there from here
is an API change, of a sort.

That seems a reasonable short-term solution. However, multiarch -dev
packages are A Good Thing in general. The way to be multiarch while still
on the default search path is to copy, move or symlink zipconf.h into
/usr/include/${DEB_HOST_MULTIARCH}.
I attach a possible debdiff. I have not tested it against any unpatched
build-dependencies, so no patch tag just yet.
