Don't you insult my /etc!!! ;-)
But, yes, /etc is the most logical place. And more and more
packages follow the ->

approach. This is probably due to the fact that what once was
/etc/bloink.cfg is now a pile of files.

Hmm, i use autoconf a lot (and actually write autoconf enabled build
scripts) but i don't think there's a "standard" option for configuration
files. But i'd need to have a closer look at the autoconf docs [and
there's a autoconf god on this mailing list i.a.].

Do you mean a shell script that calls configure with the same/consistent
options? There are several Unix(tm)/Linux(tm) distros that do exactly
that: Debian, when built from package sources basically modifies patches
the original source tree and calls configure with the "right" options.
The different flavours of BSD do similar things during their package
