New description:
The new atlas release now builds netlib lapack itself, so the lapack
tarball is now included in the ATLAS spkg.
* Updated to newest upstream source, various patches are no longer
required
* `SAGE_ATLAS_LIB=path` now searches in `path/libatlas.so` instead of
`path/lib/libatlas.so` so it works for people with atlas in `/lib64`, too.
* Threading is now enabled by default
* Flush before `os.system` (#13210)
Upstream has made some attempt at changing the layout of the shared
libraries, which is now different from the static libraries. The atlas
spkg contains a stub autoconf/libtools project that unpacks the static
libraries and repacks them into equivalent shared libraries.
By default, ATLAS will now try twice to get timings and fail immediately
if throttling is enabled. If auto-tuning fails build with
`SAGE_ATLAS_ARCH=fast`, and if that fails with `SAGE_ATLAS_ARCH=base`. On
x86, the fast and base targets are the new ATLAS generic targets x86SSE3
and x86SSE2/x86x87.
The updated cvxopt spkg fixes a blas path issue on Darwin, and is rebased
to the most recent cvxopt package to include a Cygwin fix.
There is an
[https://sourceforge.net/tracker/?func=detail&aid=3570164&group_id=23725&atid=379483
upstream problem] where compilation sometimes crashes during `xextract`
because of a buffer overflow due to small fixed-sized buffers for
filenames.
Updated '''spkg'''s:
1. [http://boxen.math.washington.edu/home/jpflori/atlas-3.10.1.p0.spkg].
2. [http://boxen.math.washington.edu/home/jpflori/cvxopt-1.1.5.p1.spkg].
'''Apply'''
1. [attachment:10508_root.patch] to the SAGE_ROOT repository
2. [attachment:trac_10508_doctest.rebased.patch] and
[attachment:trac_10508_update_atlas_docs.patch] to the Sage repository.
3. [attachment:10508_scripts.patch] to `local/bin`.
'''Remove''' the lapack and blas packages.

Comment:
I've taken Jeroen's comments into account.
It's commited on top of the latest spkg he provided as a separate commit.
See [attachment:compilers.patch].
The spkg is at:
