Bug#976950: xmds2: FTBFS on ppc64el (arch:all-only src pkg): E: Build killed with signal TERM after 150 minutes of inactivity

Source: xmds2
Version: 3.0.0+dfsg-4
Severity: serious
Justification: FTBFS on ppc64el

Hi,

During a rebuild of all packages in sid, your package failed to build
on ppc64el. At the same time, it did not fail on amd64.

I'm marking this bug as severity:serious since your package has only
Architecture:all binary packages, and should thus, in theory, build
everywhere. Failure to build on ppc64el might indicate a serious issue
in this package or in another package.

But feel free to downgrade or close if you believe that this is only a
build-time issue. (I would personnally prefer a severity:minor bug just to
track that the package can only be built on specific architectures.)

Relevant part (hopefully):

If you reassign this bug to another package, please marking it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with me
so that we can identify if something relevant changed in the meantime.
