Not exactly.  That's debian/rules what mangles with ffi.h location.

        190  endif
        191          dh_install -s --sourcedir=debian/tmp
        192
        193          mkdir -p debian/libffi-dev/usr/include/$(DEB_HOST_GNU_TYPE)
        194          mv debian/libffi-dev/usr/include/*.h \
        195                  debian/libffi-dev/usr/include/$(DEB_HOST_GNU_TYPE)/
        196
        197  ifneq (,$(filter biarch32, $(multiarch)))
        198          mkdir -p debian/lib32ffi-dev/usr/include/$(biarch_gnu_type)

And, I suppose, that would be OK, if other build process would look in
host specific directory also.  Instead pygobject relies on pkg-config.
Surprisingly, pkg-config has nothing to say about location of include
files.  Because:

        prefix=/usr
        exec_prefix=${prefix}
        libdir=${exec_prefix}/lib
        includedir=${prefix}/include

        Libs: -lffi
        Cflags:

That's exact contents of libffi.pc as shipped with libffi-dev_3.0.7-1 .
My overoptemistic attempt to fix this by adding --with-includedir has
failed.  Not because mv of debian/rules has failed to find any headers,
but because Cflags: line of libffi.pc happened to be still empty.

Thus me wonders, is that about lintian warning on ancient libtool?  I
wouldn't say that's grave, maybe important?
