[PPL-devel] SWI-Prolog test failing (only!) on powerpc

For the moment I'll just work around this failure by mostly disabling this test.
The attached patch includes this change plus an additional hack that was
necessary to make PPL build on GNU/Hurd, which doesn't define SA_SIGINFO.

Description: Upstream changes introduced in version 0.10.2-5
 This patch has been created by dpkg-source during the package build.
 Here's the last changelog entry, hopefully it gives details on why
 those changes were made:
 .
 ppl (0.10.2-5) unstable; urgency=low
 .
   * Don't build PWL on Hurd, signal handling is incompatbile.
   * Dropped versioned build dep on libgmp3-dev as even etch has a sufficiently
     new version.
   * Dropped build dep on quilt.
 .
