I should add that, when done this way, the package might expect all other
files to appear below /opt as well (for example /opt/share etc.).
If you only wanted the lib/ directory to appear someplace else, then I
think you can achieve this by even uglier

  configure --prefix=/opt/foo --libdir=/opt/lib --enable-fast-install \
        [OPTIONS]
  make
  make install DESTDIR=/tmp
  mv /tmp/opt/lib/* /opt/lib/*  # or similar; ensure target dirs exist
  mv /tmp/opt/*  /opt/foo       # see above
  # create symlinks
  ./libtool --mode=finish /opt/lib

Note this is untested, but it'd be good to know if it causes trouble
with existing packages.  :)

Cheers,
Ralf
