  * milestone:  => sage-5.10

> longer, I will revert #10508.

New description:

 There are some problems with generic binaries (`SAGE_FAT_BINARY=yes`) in
 the new ATLAS spkg. In order not to delay the release of Sage 5.10 any
 longer, I will revert #10508.

 On cicero (Fedora 16 i686), the build fails:
 
[http://build.sagemath.org/sage/builders/Skynet%20cicero%20%28Fedora%2016%20i686%29%20bin/builds/90/steps/shell_5/logs/atlas]

 Note lots of "Illegal instruction" messages, proving that this likely is
 not a generic binary, unlike what it should be.

 On arando (), the build works but there is doctest failure:
 {{{
 sage -t devel/sage/sage/matrix/matrix_double_dense.pyx
 **********************************************************************
 File "devel/sage/sage/matrix/matrix_double_dense.pyx", line 3823, in
 sage.matrix.matrix_double_dense.Matrix_double_dense.is_positive_definite
 Failed example:
     H.is_positive_definite()
 Expected:
     True
 Got:
     False
 **********************************************************************
 }}}
