A dependency on gcc-multilib does not work for cross compilation. This
can be worked around via gcc-multilib-TRIPLET. Unfortunately, those
packages are not presently Multi-Arch: same. They really should be as
their target architecture is encoded into the package name. I'm
attaching a patch for your convenience.

Helmut

your patches seem to be incomplete by design ... seems like a bad habit
often seen before as well.  Adding this attribute for the other multilib
packages as well.

Matthias

Hi Matthias,

It is difficult to strike a good balance. Rather often, I sent a more
comprehensive patch (to other maintainers) and got an angry reply that I
was doing too much. So I tend to err on fixing the one thing that really
is broken and not touching other pieces.

Another angle is the success rate. For packages where the maintainer
lets my patches sit for years I tend to invest less into patches than
for packages where the maintainer quickly responds with comprehensive
feedback.

Again, I am left in the dark as to whether you are intending to add the
foreign flag to the other multilib packages yourself or whether you are
asking me to update the patch.

If you were able to more timely feed back what changes you want about my
patches, the submitted patch quality would probably improve.

Helmut
