OK! BTW, It took me some weeks to identify this very problem...

Well, `ar' uses the plugins to be able to handle more binary formats;
for daily use it's not necessary to have it.

For `ar', the actual version of gcc doesn't matter; you can always
link to the most recent version of `liblto_plugin.so', according to
the `ar' or `gcc' documentation (right now I don't remember which
one).
