<p>
Whenever the <b>host OS and the target OS differ</b>, you need to specify
<tt>TARGET_SYS</tt> or you'll get assembler or linker errors. E.g. if
you're compiling on a Windows or OSX host for embedded Linux or Android,
you need to add <tt>TARGET_SYS=Linux</tt> to the examples below. For a
minimal target OS, you may need to disable the built-in allocator in
<tt>src/Makefile</tt> and use <tt>TARGET_SYS=Other</tt>.

You can cross-compile for an <b>ARM target</b> on an x86 or x64 host
system using a standard GNU cross-compile toolchain (Binutils, GCC,
EGLIBC). The <tt>CROSS</tt> prefix may vary depending on the
