Bug#819995: haskell-werewolf: FTBFS: werewolf-test: unknown RTS option: -N

[Aaron M. Ucko]

Source: haskell-werewolf
Version: 0.5.1.0-1
Severity: important
Justification: fails to build from source

Builds of haskell-werewolf for several architectures failed when
trying to run tests, with

  Running debian/hlibrary.setup test --builddir=dist-ghc --show-details=direct
  Running 1 test suites...
  Test suite werewolf-test: RUNNING...
  werewolf-test: unknown RTS option: -N
  werewolf-test:
  werewolf-test: Usage: <prog> <args> [+RTS <rtsopts> | -RTS <args>] ... --RTS <args>
  Test suite werewolf-test: FAIL
  Test suite logged to: dist-ghc/test/werewolf-0.5.1.0-werewolf-test.log
  0 of 1 test suites (0 of 1 test cases) passed.
  /usr/share/cdbs/1/class/hlibrary.mk:154: recipe for target 'check-ghc-stamp' failed
  make: *** [check-ghc-stamp] Error 1
  dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2

Specifically, this error occurred on the release architectures arm64,
mips, mipsel, ppc64el, and s390x, and on the non-release architectures
hppa, mips64el, sparc64, and x32.

Could you please take a look?

Thanks!
