Just added another portage patch for preserve-libs on AIX
(grobian please include this in some next portage release),
to not break with archive members being import files (=plain text),
which is "Variant B2" I eventually may switch to.
This works for any shared-library-variant and thus should provide
a smooth upgrade when I change the ELT-patches for aix.
So if you already have =portage-2.2.00.15742 merged, please
sync and remerge portage, to keep your AIX prefix healthy.
