http://bugs.debian.org/482239
* Non-maintainer upload.
* No longer try to detect (using /proc/cpuinfo when available) how many
  CPUs are available, fixing the FTBFS (due to -j0) on various platforms
  (Closes: #477353). The right way to do it is to support parallel=n in
  DEB_BUILD_OPTIONS (see Debian Policy §4.9.1), and adequate support has
  been implemented.
* Add patch to fix FTBFS due to the build system now refusing to handle
  whitespaces (Policy CMP0004 say the logs), thanks to Andreas Putzo who
  provided it (Closes: #482239):
   - debian/patches/fix-cmp0004-build-failure.dpatch
* Remove myself from Uploaders, as requested a while ago, done by Luk in
  his 2.2.0-2.1 NMU, which was never acknowledged.
