Automatic Office Home detection not working on 64bit Linux system (Fedora 20)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call OfficeUtils.getDefaultOfficeHome()

What is the expected output? What do you see instead?
Expecting: /usr/lib64/libreoffice
Returning instead: null

What version of the product are you using? On what operating system?
3.0-beta-4 on a Fedora 20, 64bit

Please provide any additional information below.
The code inside OfficeUtils looks in the right locations, but for 64 bit Linux, 
does not consider the fact that instead of /usr/lib, it should use /usr/lib64 
instead. For Windows, 64 bit checks exist, but for Linux they don`t.
