Bug#840454: fflas-ffpack: FTBFS: several tests fail

Source: fflas-ffpack
Version: 2.2.2-2
Severity: serious
Justification: fails to build from source

Builds of fflas-ffpack 2.2.2-2 for armel, mips, powerpc, and s390x, and
the non-release architectures hppa, ppc64, and sparc64, all failed with
similar test-suite errors involving Modular<Integer>, as detailed at

https://buildd.debian.org/status/logs.php?pkg=fflas-ffpack&ver=2.2.2-2

Previous 2.x builds have also been failing on these architectures, so
they all still have version 1.6.0-1 in unstable.

Specifically:

- On most of these architectures (all but armel), test-lu reports
  failures of both test cases involving Modular<Integer>.  FWIW, for
  other types, it issues a lot of warnings of the form "120xN pluq
  verification failed!"  (However, those test cases all pass, and the
  Modular<Integer> tests encounter no such warnings.)

- On most of these architectures (again, all but armel), test-echelon
  crashes after performing three ModularBalanced<int64_t> tests, having
  presumably moved on to Modular<Integer>.  These crashes take the form
  of a bus error on hppa and a segmentation violation on the remaining
  architectures.

- On all of these architectures, the test-rankprofiles test case
  involving Modular<Integer> fails, with no details reported.

- On all of these architectures, the test-fgemm test case involving
  Modular<Integer> fails, with copious diagnostic output.

There was one additional error on sparc64, which I'll report separately
since it didn't occur anywhere else and wasn't obviously related.

Could you please take a look?

Thanks!
