If I understand correctly, this build issue is not specific to riscv64,
so we do not need d-riscv list usertags tagged by riscv64 for it special.
We use usertag to classify a certain issues which has the same, like
the behavior or cause to let developer/maintainer has an overall understanding.
Here you can visit d-riscv list usertag[0] to have a look at issues related 
to riscv64.

In theory, as porters, you can cc all architectures(tagged with $arch)
to let other porters to realize this. But if looking at this[1] again, I
think you will not to do this.:)

BTW, when submitting patch to Debian, it is encouraged to obey Patch
Tagging Guidelines[2]. When you filling these terms of dep3 you will
find one interesting entry: forwarded or upstream unless this issue is
debian specific. In other words, we can forward the patch to upstream
when send to debian meantime.

Thanks for your contribution!
