things from the top level.
* configure.ac (GLIBCXX_IS_NATIVE): Determine earlier and re-order.
Comment out the conditionals for CANADIAN and GLIBCXX_BUILD_LIBMATH
(currently unused). Strip the fake-VPATH shell fragment from
automake-generated rules, if present.
* linkage.m4: Add comment.
* fragment.am: New file, containing factored-out common settings.
