/usr/lib/powerpc64le-linux-gnu/libxslt.so.1: invalid ELF header

[Mike Rushton]

The follow error occurs when trying to run canonical-certification-server on a Power 8:

ubuntu@powereight:~$ canonical-certification-server

The program 'plainbox' is currently not installed. You can install it by typing:
sudo apt-get install plainbox

So it looks like not a plainbox bug, but one with libxslt. I asked Mike to please test with another program linked to libxslt:

14:37 < roadmr> leftyfb: can you apt-get install xsltproc
14:37 < roadmr> leftyfb: then run "xsltproc --dumpextensions" ?
14:38 < leftyfb> ubuntu@powereight:~$ xsltproc --dumpextensions
14:38 < leftyfb> xsltproc: error while loading shared libraries:
                 /usr/lib/powerpc64le-linux-gnu/libxslt.so.1: invalid ELF header

I'm marking this as invalid. It looks like gcc bug or something weird in ppc in general. Feel free to reopen if we can do something about it.
