[Debian-med-packaging] Bug#883047: canu: Build-depend on mhap to avoid uninstallable binaries

[Steve Langasek]

Package: canu
Version: 1.6+dfsg-1
Severity: important

Dear Afif,

In Ubuntu, we observed that the canu package was not releasable because it
generates per-architecture binary packages with a transitive dependency on
libssw-java, which is only available on amd64.

To work around this issue, I have added an "artificial" build dependency on
mhap to the canu package in Ubuntu, so that the package will not build on
architectures where mhap is not available.

This problem also affects canu in Debian, and is the reason that canu has
not migrated to Debian testing; so I would suggest applying this patch in
Debian as well.

Cheers,
