Jenkins linux32

[Emma.Davenport]

Hi,
As a part of the pre-deployment to Gerrit I cross-compile for different 
platforms. For 32bit linux I use a 32bit ubuntu 16.04 docker container. But 
there seems to be some differences in how wchar_t type variables are handled 
between my docker container and the jenkins host for 32bit linux builds. What 
base image is used for these builds on jenkins?
Thanks
