Some ideas.

-m32 is missing in the CFLAGS (this belongs in configure-options, not in make 
options) and
the 32 bit version of the qt library is not installed or is installed, but not 
used. this is called emul-linux-x86-qtlibs on my system, but i have never 
tried building against these. you probably need to explicitly specify the 
path for the linker.
