the problem is not just performance, but having a readable configure.ac
file (or at least, a non-unreadable one). The MKL libraries are a major
contributor to entropy. I took the point of view that from now on, only
"recent" versions of MKL are supported, and only if they are properly
installed (i.e. with environment variables LD_LIBRARY_PATH and
LIBRARY_PATH pointing to them), are supported. "Recent" in the above
sentence means "later than those installed on my work PC 2.5 years
ago", so not exactly "the latest and the greatest". Of course there can
be mistakes in the configure.ac file, which are revealed by a careful
inspection of the config.log file (admittedly, not a fun reading).
