4. SliTaz uses the sysroot method
( 1). cook.conf
http://hg.slitaz.org/cookutils/file/3f5c9e87f05d/cook.conf

51 # SliTaz uses the sysroot method, this tells GCC to consider dir as the root
52 # of a tree that contains a (subset of) the root filesystem of the target
53 # operating system. Target system headers, libraries and run-time object
54 # files will be searched in there. Cook will use the tools and sysroot in
55 # the CROSS_TREE for cross compiling. Example: CROSS_TREE="/cross/$ARCH"
