 As reported in [https://bugs.debian.org/810859 Debian Bug #810859]:
 > postgis fails to build because the testcases fail, e.g.:

 > The reason why this fails is, because parisc/hppa and mips have
 different floating point representations for NAN (not-a-number).
 > The attached patch fixes it for hppa (tested!) and most likely for mips
 as well (untested).
 > Can you apply this patch for the next upload and/or push it upstream ?

 > PS: For hppa postgis will probably still fail to build, but that's most
 likely a problem in postgres not postgis (still working on it).
