Bug#1120413: scotch: error with no remote interface in ptscotch tests

[Drew Parsons]

Package: scotch
Version: 7.0.10-1exp2
Followup-For: Bug #1120413

Worth mentioning that scotch debci tests are passing with pmix 5.0.9.
Only the buildd environment is affected.

This means the debci environment does have remote interfaces, not only
the lo interface.

The problem affects chroots where only lo is available, which is the
case for our buildd environments (no internet access from buildds).

This makes me think more this is an upstream bug in pmix 5.0.9:
foreign tool support might be active by default, but that shouldn't
necessarily mean it is mandatory.
