Upgrading and testing in a range of different configurations, for all the
packages sharing the toplevel code, is quite tricky (though it's libtool
that's the most problematic and where we know that on any upgrade we need
to revert a libtool change for sysroot handling that conflicts with GCC
sysroot handling).
