@ -240,7 +240,10 @@ 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.
<tt>libc6-dev-i386</tt> on Debian/Ubuntu) and build a 32 bit host part
(<tt>HOST_CC="gcc -m32"</tt>).
(<tt>HOST_CC="gcc -m32"</tt>). On some distro versions, multilib conflicts
with cross-compilers. The workaround is to install the x86 cross-compiler
package <tt>gcc-i686-linux-gnu</tt> and use it to build the host part
(<tt>HOST_CC=i686-linux-gnu-gcc</tt>).

You need to specify <tt>TARGET_SYS</tt> whenever the host OS and the
