"The GNU Makefile-based build system allows cross-compiling on any host for any supported target, as long as both architectures have the same pointer size. If you want to cross-compile to any 32 bit target on an x64 OS, you need to install the multilib development package (e.g. libc6-dev-i386 on Debian/Ubuntu) and build a 32 bit host part (HOST_CC="gcc -m32")."
