[Debian-med-packaging] Bug#780428: beast-mcmc: restrict arch from all to amd64

[Andreas Beckmann]

Package: beast-mcmc
Version: 1.8.0-1
Severity: normal

Since beast-mcmc is only installable on amd64, there is no use for it
being an arch:all package, arch:amd64 would be sufficient.

The libnucleotidelikelihoodcore0 which imposes this restriction is from
the same source package anyway ...
