Trilinos, specifically Kokkos, only support 64bit-architectures. The build failure on i386 is therefore expected.
I've compiled trilinos on ppc64el and could no reproduce the error [1]. Perhaps that's something that's accidentally been fixed in the meantime? Cheers, Nico [1] https://launchpadlibrarian.net/261874013/buildlog_ubuntu-yakkety-ppc64el.trilinos_12.7~20160527031607-e5abd8d8-1yakkety1_BUILDING.txt.gz
