 Would there be much more involved than

 mkdir objdir
 cd objdir
 /path/to/srcdir/configure <options>

 ? This is already possible with current autoconf/automake, but custom rules
 for non-standard targets/files may need adjustment. Running configure as
 above from a user id different from the one that owns the source tree will
 help to find such problems.
