I don't have an easy answer but...
You probably need a larger sample size to determine if adding arch args to
CPPFLAGS is a good idea or not. As a practical matter, it's only worth doing if
it solves more problems than it causes.

configure scripts can very pretty extensively based on the individual project.
For an old project at $WORK, I adapted an existing configure build setup to
build universal (ppc/i386) properly and by default on MacOS X (we didn't do any
cross-compilation).
There are plenty of ports that build OK without using munivsersal. muniversal
is very useful for ports where 'correcting' the build to not require two runs
(plus lipo) is too much work, though.

I think mostly you're seeing that building anything that isn't very simple is
often hard, unless the upstream developers have put some effort into making it
work correctly (and for configure based builds, multiple arch and/or
cross-compiling is not very simple).
