The point of our autoconf macro is to allow 'shortcuts', such that the argument

--with-layout=Foo

rewrites prefix/libexec/etc to a specific set of values (dictated by
our file config.layout) and then have explicit passed parameters
override those 'layout' files.

It looks like you switched the docs to recomend using AC_ARG_ENABLE,
but I'm not sure how that would address our issue.

We might be able to delay the AC_CANONICAL_SYSTEM invocation until
after we process the layout options - but I seem to recall a reason
why we delayed invoking those macros.

Thanks.  -- justin
