A lot of manual include path to executable. This path depend from vendor 
and OS. The correctly written documentation has to use proper paths
For instance /bin/sh is correct for most system but on some linux based 
OS-es it is /system/bin/sh .

So the rule to put into source tree generated files (documentation) 
prevent parallel build for multiple host or target platforms.
