There is unfortunately just no universal standard for this (the alleged
MS-style standard of forever resigning PREFIX/lib to be 32-bit even on
64-bit native systems is - rightfully - rejected by a lot of
distributions).

That said, multiarch wasn't really considered much when this was
written.  It could perhaps be improved, but I don't think there is any
single right thing that could be said here.  Suggestions/patches
welcome...

As with anything, though, you can install to wherever and set LV2_PATH
to whatever is appropriate, so I don't think it's a huge deal.  Maybe
the page should be revised to not suggest that you *have* to use
exactly these paths in all cases?
