moving libhandle to /usr

[Christoph Hellwig <hch@xxxxxxxxxxxxx>]

Currently we install the versioned libhandle into /lib by default,
and all other libraries into /usr.  Given that no program in / actually
uses libhandle this seems rather awkward to me.  From Mike's comments
in the past I think Gentoo already installs it into /usr anyway.

Is there anything speaking against moving all libraries to /usr and
switching Debian/Fedora to that aswell?
