We were corrupting r2 because the local entry wasn't being
setup correctly.

d117dfd505 Change bad usage of "asum" to "sum" in ZARCH versions of ?sum 
The ZARCH implementations of ?sum contain a cut & paste-error: An inline
assembly argument is named "sum", but the assembly references "asum"
instead.  The mismatch causes a build error.  This is fixed.

0caf1434c9 Fix the integer overflow issue for large matrix size 
For large matrix, e.g. M=N=K, and M>1290, int mnk=M*N*K will overflow.
This will lead to wrong branching to single-threading. The performance
is downgraded significantly.

b3ac6ee222 Define alternate kernels for big-endian PPC970 
The altivec versions of SGEMM and CGEMM fail most test in LAPACK-TESTING when compiled for big endian, STRSM/CTRSM even cause segfaults. The rot kernels either fail the corresponding utest or lead to failures in LAPACK-TESTING.
