Description: Skip optimizations for big-endian PowerPC.
 Some of the existing optimized files/cases for PowerPC
 contain assembly instructions with implicit big-endian
 behavior - thus incorrect for the little-endian mode -
 incurring tests failures during the build (i.e., FTBFS).
 This is being worked on; this is the workaround for now.
 .
 Note: this is an alternative for Michael Normand's patch
 'atlas.3.10.2-ppc64le_do_not_use_files_with_lvx.patch',
 in order not to touch file lists/indexes, but only C 
 source code, so the C preprocessor can avoid code per-arch.
 .
