On recent Debian (ones with multiarch), you build for 32-bit by
installing the relevant 32-bit devel libraries and an appropriate
compiler (probably called something like i386-crossgcc).
On earlier Debian releases, this is done in a chroot.
Just asking for -m32 will get the compiler to generate 32-bit machine
code but then it will try to link with the 64-bit libraries and all is
doom.
