Yes, it does:
    /usr/bin/gcc -idirafter /home/ymorin/dev/buildroot/O/host/usr/include
        -L/home/ymorin/dev/buildroot/O/host/lib
        -L/home/ymorin/dev/buildroot/O/host/usr/lib
        -Wl,-rpath,/home/ymorin/dev/buildroot/O/host/usr/lib
        -Wp,-MT,cpio.o,-MD,./.cpio.o.d
        -std=gnu99
-->     -m32                <----- Here. ;-)
        -march=i386
        -mpreferred-stack-boundary=2 -fno-stack-protector -fwrapv
        -freg-struct-return -Os -fPIC
        -fno-exceptions -fno-asynchronous-unwind-tables -fno-strict-aliasing
        -falign-functions=0 -falign-jumps=0 -falign-labels=0 -falign-loops=0
        -mregparm=3 -DREGPARM=3
        -W -Wall -Wstrict-prototypes -fomit-frame-pointer
        -D__COM32__
        -nostdinc
        -iwithprefix include
        -I/home/ymorin/dev/buildroot/O/build/syslinux-6.02/com32/libutil/include
        -I/home/ymorin/dev/buildroot/O/build/syslinux-6.02/com32/include
        -I/home/ymorin/dev/buildroot/O/build/syslinux-6.02/com32/include/sys
        -I/home/ymorin/dev/buildroot/O/build/syslinux-6.02/com32/gplinclude
        -c -o cpio.o
        /home/ymorin/dev/buildroot/O/build/syslinux-6.02/com32/libupload/cpio.c

If not, then I get the usual 'bits/predefs.h' problem that is solved by
installing gcc-multilib.

Yann E. MORIN.
