(Missing configure line and "cc -v" output.)
configure will select the correct architecture for your system's default
compiler if you do not explicitly set a compiler with "--cc=".
To compile for 32bit on a 64 bit system, you can for example use:
./configure --cc='cc -m32'
Afaict, --arch is only useful if you cross-compile.
