Bug#835406: trilinos: FTBFS on 32-bit architectures

[Graham Inggs]

Control: -1 patch


Hi Aaron

I cloned bug #815725 as a wishlist bug for 32-bit architectures, since 
upstream only want to support 64-bit.  I was able to fix the use of x86 
assembly on other 64-bit architectures and closed the original bug.  New 
builds were successful on arm64, mips64el, alpha and sparc64.  Trilinos 
also built on s390x in Ubuntu where they have a working libtbb for s390x.

I did some further experimentation and came up with a patch (attached) 
to build Kokkos (and thus a complete Trilinos as well) on 32-bit 
architectures.
I have successfully built trilinos on i386 and armhf, and builds on 
amd64, arm64 and ppc64el remained successful.  Ithen successfully built 
deal.II against the new Trilinos packages on all of the aforementioned 
architectures, although the deal.II tests eventually timed out on armhf.

If there are no objections, I will upload Trilinos including this patch 
within this week.

Regards
Graham
