Comment(by drkirkby):
I'm still puzzled by the logic of making changes which:
* Make it much more difficult to speed up the Sage build process by
removing the small amount of Python necessary to start the ATLAS build
earlier.
* Implementing changes, some of which are unnecessary if ATLAS is
updated.
IMGHO, the two most logical things to do the the ATLAS package are:
1) Update the ATLAS version, which has support for many new CPUs and so
allow a lot of the Sage-specfic CPU hacks to be removed. It also has the
facility to use a generic set of tuning parameters.
2) Remove the few lines of Python, so ATLAS no longer depends on Python.
Then the build of ATLAS can be started much earlier. This would speed up
the Sage build, as ATLAS would be building for longer. ATLAS is ofgten the
only item being built, so is a bottleneck.
This patch seems a backward step to me.
