Using LAPACK_SRC approuch will not work as some LAPACK source files need
to be compiled without optimization flags but currently scipy.distutils
does not support switching off optimization for certain files. Using
`config_fc --noopt` would switch off optimization for all Fortran sources.
So, you need to build at least LAPACK library manually, see `Building
the LAPACK library` section in
