In that case you should use a custom configure command:

../../../platforms/unix/config/configure CC="gcc -m32" CXX="g++ -m32" --without-npsqueak CFLAGS="-g -O2 -msse2 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DNDEBUG -DITIMER_HEARTBEAT=1 -DNO_VM_PROFILE=1 -DCOGMTVM=0 -DDEBUGVM=0" LIBS=-lpthread

The docs lack a ../ from the beginning of the command btw.
