    ncurses-native: install to libdir, not base_libdir

breaks python ncurses support.

Any ideas on proper fixing? For myself I revert this locally and
everything works perfectly.
(I think .so files and .a archives should be in usr/lib while .so
can go to /lib which is not the case with current ncurses.)
so mv in do_install should be sufficient, not --libdir=${base_libdir}.

All the best,
S.
