Packaging on a 32-bit and running on 64-bit

[Developer]

Hi all,

I am using a 32-bit Debian Linux for development and would like to 
deploy on the same linux but for the 64-bit variant. What do I have to 
take in mind?

Trying to execute a package build on 32-bit at the 64-bit system caused 
several errors (e.g. incompatible 64-bit IO.so found)

Thanks in advance,

Werner
