    gnu: lapack: Install libraries to PREFIX/lib, not PREFIX/lib64.
    
    This fixes a regression introduced in
    ef39a17717a10a7f406730258acfdb07934c7255, which would break
    python-scipy ("undefined reference to `zungqr_'").
    
    * gnu/packages/maths.scm (lapack)[arguments]: Add
    "-DCMAKE_INSTALL_LIBDIR" to #:configure-flags.
