Indeed the 32bit build fails, googling suggests to use --enable-pic
but it results in an asm error :

yasm -O2 -f macho -DPREFIX -DHAVE_SSE3 -D__PIC__ -Icommon/x86/ -o
common/x86/cabac-a.o common/x86/cabac-a.asm
common/x86/cabac-a.asm:91: undefined symbol `fakegot' (first use)
common/x86/cabac-a.asm:91:  (Each undefined symbol is reported only once.)
make: *** [common/x86/cabac-a.o] Error 1
