python-numpy build fails only if lapack is built before python-numpy
itself, and this doesn't always happen because lapack dependency is
missing in BR2_PYTHON_NUMPY_DEPENDENCIES. clapack is present
instead, but it's wrong since we're checking $(BR2_PACKAGE_LAPACK) not
$(BR2_PACKAGE_CLAPACK). Once clapack is substituted with lapack build
failure is due to missing BR2_PACKAGE_LAPACK_COMPLEX that
provides some functions in lapack libraries needed by python-numpy.
So:
- substitute clapack with lapack in BR2_PYTHON_NUMPY_DEPENDENCIES when
BR2_PACKAGE_LAPACK = y
- substitute ifeq check "$(BR2_PACKAGE_LAPACK),y" with
"$(BR2_PACKAGE_LAPACK_COMPLEX),y" because python-numpy needs COMPLEX
functions and BR2_PACKAGE_LAPACK_COMPLEX inherits BR2_PACKAGE_LAPACK
