add configure option --with-root-libdir

This allows the development link libraries to be installed in
/usr/lib, while the run-libraries are installed in /lib, which is
required by Debian policy.  This can be done via:

    configure --prefix=/ --libdir=/usr/lib --with-root-libdir=/lib

The technique of working around libtool's inflexibility is borrowed
from util-linux.
