There are timestamps and build IDs and more which, unless
tinkered with, will mean that building ANY package at two
different times will have (non-functional) differences that
prevent an exact binary duplicate from ever existing.
Similarly, with parallel threaded (-j N) build systems, a
Makefile might comclude one time that sub-element FOO was done
first, otehr times sub-element BAR, and so to traverse a build
path in differing orders. Not anything invidious, but not
'identical' either
