I'm building Linux 64bit non-standalone viewers since 2 1/2 years now, 
in gerneral once all libraries where in place there has been most of 
the time no extra work - its just a Linux version with different 
libraries. Looking at the download couter, a bit more than half of all 
Imprudence Linux users are using the 64bit version).

The patch I'm using for autobuild is trivial 
https://bitbucket.org/ArminW/autobuild-kokua/changeset/d653428ae98e - 
to build 64bit export AUTOBUILD_PLATFORM_OVERRIDE=linux64  ("linux64" 
is inherited from viewer 1 time, there have been some package 
references in the install.xml file).
Adding a linux64 project to the viewer isn't that much of a difference, 
see for example Boroondas draft repository:  
https://bitbucket.org/boroondas/viewer-development-linux64-draft .
I added also a linux64 project to many of the 3p libslibrary, though not 
yet all of them,  see https://bitbucket.org/ArminW . Probably some bits 
and pieces would need changing if someone wants to prepare versions for 
LL use, but for sure for that purpose they can already save a lot of 
time in the way they are now. If someone or a team wants to take the 
job of getting them through the codereview process I'm glad to 
contribute my work as is.
