Add 32bit build in travis-ci config

[strk]

I understand the current travis setup is building using CMake and Automake with both GCC and clang, but only as 64bit. If that's correct it would be nice to add a 32bit build to the matrix.

Presumably 32bit and 64bit above have an implicit "Intel" qualifier :-) It would be really nice to have a CPU that is not Intel, and one that is big endian.

It is great to see regular builds with a compiler other than gcc, too.

I'm afraid other-than-intel cannot be done with the online travis-ci service. Need to look at our Jenkins bot or at the future buildbot (if any). Would you be willing to provide a non-intel slave host for either jenkins or buildbot ?

[mloskot]

FYI, AFAIR, we didn't have any non-Intel slave attached to the OSGeo Buildbot.

[strk]

Slaves can be added/removed, we don't have anything attached to the OSGeo buildbot because there's no OSGeo buildbot master running right now ( ​http://trac.osgeo.org/osgeo/ticket/1214 )

[mloskot]

@strk I know what's the current state (no Buildbot) and that slaves can be attached.

I just observed that, at times we maintained Buildbot alive, we did not have any non-Intel architectures. Thus, resurrecting Buildbot is not going to automatically change this situation, as there are nom, as had never been, non-Intel machines at OSGeo available. Neither we had any non-Intel slaves from users.
