Bug#949880: pysph needs hinting into testing

[Adrian Bunk <bunk@debian.org>]

Package: release.debian.org
Severity: normal

Issues preventing migration:
uninstallable on arch arm64, autopkgtest delayed there
Additional info:
pysph-viewer/i386 unsatisfiable Depends: python3-pysph

The first issue is caused by #918620.
The second issue is "not installable on i386", which needs hinting.

Root cause is #948736, which makes the package FTBFS with Python 3.8
on all release architectures except amd64.
IOW, it builds on all release architectures where it is being used. ;-)

Thanks in advance
