Autoconf always assumes it is in topdir.  I suspect there's no easy way to work 
around
that.

Oh.  Well,


     topdir/
         src/
             package1/
             package2/
         arch1/
         arch2/

Would be a lot easier.  Then the magic is just


     cd topdir/arch1
     ../configure

and the following structure will be created:


     arch1/
         src/
             package1/
             package2/

Maybe that's not exactly what you wanted, but Autoconf is already set up to 
handle it.
Note that all the source files not generated by configure will still be under 
topdir/,
not topdir/arch?, and a properly constructed Makefile will still be able to 
find them.
The idea is that the build area will mirror the structure of the source area, so
topdir/arch1/src/package1 should have files built from sources in
topdir/src/package1...

These aren't separate projects, are they?  Such that they could each have their 
own
configure script and a controlling Makefile that would cause a build to descend 
into
each arch-specific directory, run the appropriate configure script, and then 
run each
build?
