[yocto] Usage of yocto on different (production vs debug) scenarios

[Burton, Ross]

Very curious as to what book said that, because *any* example of that
happening is a bug in the recipe itself.  I wouldn't listen to it: the YP
autobuilder has a shared sstate for three distributions * four
architectures * two libc implementations and doesn't have problems.
