New description:
Different pkgs find ATLAS (or equivalent libs e.g. on OS X and Cygwin)
libs in different ways.
In particular the situation is broken on Cygwin.
The one we tweak ourselves are:
* ATLAS when we pass SAGE_ATLAS_LIB to decide what to copy/symlink
* fflas-ffpack
* iml
* R
* the Sage library through SAGE_BLAS and module_list.py and its BLAS/BLAS2
madness
Other pkgs depend on a BLAS implem but are autonomous.
My proposal before a pkgconfig solution gets available at #17075 is that
when ATLAS spkg-install script is run it decides what should be used once
and for all and other packages use this information (like used to be done
a little bit when the linbox spkg-install script wrote `echo $LINBOX_BLAS
> $SAGE_LOCAL/share/cblas_config`)
