That's a fine distinction, that makes little sense to me -- the total 
number of ports, which can not ever work on some architecture is, 
probably, a couple dozen... It is also not mentioned in the Handbook 
<http://www.freebsd.org/doc/en/books/porters-handbook/dads-noinstall.html> 
at all:

    If a port should be marked IGNORE only on certain architectures,
    there are two other convenience variables that will automatically
    set IGNORE for you: ONLY_FOR_ARCHS and NOT_FOR_ARCHS. Examples:

    ONLY_FOR_ARCHS= i386 amd64
    NOT_FOR_ARCHS= ia64 sparc64

    A custom IGNORE message can be set using ONLY_FOR_ARCHS_REASON and
    NOT_FOR_ARCHS_REASON. Per architecture entries are possible with
    ONLY_FOR_ARCHS_REASON_/ARCH/ and NOT_FOR_ARCHS_REASON_/ARCH/.

Thus, I still think, using these knobs is better -- especially, when 
doing otherwise requires splitting bsd.ports.mk into 
bsd.ports.{pre,post}.mk. Yours,
