Thanks for your answer.

I fixed my problem, but not being a developer i wouldn't be able to 
identify the bug more precisely. I just force CC and CXX variable to 
include the -m32 flag.

After ./configure, I :

sed -i -e "s@= gcc& -m32 at g" -e "s@= g++@& -m32 at g" $(find . -name "Makefile")

... to force gcc and g++ to build in 32-bit mode.

Apparently, Qt had the same bug as one of their dev told me that he had 
to modify the CXX variable design to separate compilers from their 
flags. I don't specify -m32 in compiler flags but directly when calling 
the compiler so I suppose the problem come from there.

Anyway, I still believe this is a bug (all of my 360 packages always 
compiled fine this way), but we know of a workaround now.

The 64-bit build compiles fine FYI.
