Linker flags for MKL library are not set correctly (migrated from Trac #1381) #2934

Original ticket http://projects.scipy.org/numpy/ticket/1381 Reported 2010-01-28 by trac user neinhues, assigned to atmention:cournape.

In numpy-1.4.0/numpy/distutils/system_info.py

somebody tried to link both against 32 and 64bit libraries which does not work. A patch is attached.

Please note: Using the MKL libraries with numpy only works if Python is also linked against the MKL libraries. The reason is that the MKL libraries don't work for dl-opened libraries like Python extensions

Linking against MKL certainly seems to work for many people like this. Christoph, can you comment on this?
