New description:

 The spkg-install code of atlas spkg is structured as follow (from line
 192):

 {{{
 if SAGE_FAT_BINARY == 'yes':
     arch = 'HAMMER'
 elif SAGE_ATLAS_ARCH is defined:
     arch = 'SAGE_ATLAS_ARCH'
 }}}

 It has the effect not to take the SAGE_ATLAS_ARCH variable into account
 when SAGE_FAT_BINARY is set to 'yes'. I consider it as a bug, since on may
 want to build a fat binary for an architecture that is not HAMMER (for
 example, one may want to build a fat binary able to run on Pentium 3).
