Problem with linux-32 bit

[megies]

Trying to run tests on the built Anaconda installer for linux-32 bit is running into problems (e.g. https://travis-ci.org/obspy/anaconda-installers/jobs/253951756):

Need to check if just the installing doesn't work or if the built installer is broken too..

It seems like building or at least testing installers on Travis 32bit won't work..

• https://travis-ci.org/obspy/anaconda-installers/builds/254221839
• https://travis-ci.org/obspy/anaconda-installers/jobs/254221841#L288
• https://travis-ci.org/obspy/anaconda-installers/jobs/254221844#L257

We'll probably have to build installers for 32bit Linux using our docker setup..
