They don't, even though it seems so. The Makefile is *read* 
after /etc/make.conf. The Makefile sets this variable unconditionally, 
therefore cannot be overridden by anything that is read before the Makefile.
If the Makefile defined it like so:
NOT_FOR_ARCHS?=alpha ia64

then /etc/make.conf would work, since the variable is defined at the time the 
Makefile is read.

It is and since Makefile.local is read *after* the Makefile, you can override 
the variable there.

Problem with today's modular software: they start with the modules
    and never get to the software part.
