#### Description

We use to have uname for build arch detection which was wrong and caused its own issues (SNOW-429 which also fixed this) now we have no build arch detection and just force WORD_SIZE=32 in the autobuild control file, which is IMHO a regression.

For standalone builds we really desire automatic arch detection as it required to compile the viewer on 64 bit machines (as you are linking 64 bit libraries). We can probably use cmakes own arch detection but we must ensure the default case of a non-standalone build still uses 32 bit by default.
