Ok, I've pushed the fix, but I've left the changelog as "UNRELEASED"
because there are some issues that I prefer to leave for you:

- This is contrib, does it really need a binary build?

- The package currently FTBFS on i386, and autopkgtests apparently
need it:

https://qa.debian.org/excuses.php?package=amgcl

- Also, there is a build-dependency on libparmetis-dev which is
not generally available:

https://buildd.debian.org/status/package.php?p=amgcl

Maybe it's time to make the package amd64 only?

Thanks.
