[Qbs] How build 32 bit application on 64 host OS

[Карелин Павел]

Hi,

I'm working in Ubuntu 14.04, 64 bit. I use QtCreatir 4.4.1
Now I needed to build a small qbs project for two architectures: intel 
64 and 32 bits.
I have installed qt4 system libraries, 64 and 32 bits respectively. 
qmake - only 64 bits.
Simultaneously install the qmake to 64 and 32 bits - I can not, packages 
are mutually exclusive.
Tell me how to assemble the project simultaneously for 64 and 32 bits?
