In OpenMP threading, preallocate the thread buffer instead of allocating the buffer every time. This patch improved the performance slightly.

Refs #174 . Fixed the overflowing buffer bug of multithreading hbmv and sbmv.
Instead of using thread 0 buffer, each thread uses its own sb buffer.
Thus, it can avoid overflowing thread 0 buffer.

add a sanity check on the detected cpu type
if we have 64 bit pointers we can't have a 32 bit cpu, so fall back to
the 64bit cpu fallback (prescott)
E.g. the cpu detection fails in amd qemu64 emulation (family 6 model 2)
causing it to use the uninitialized gotoblas_ATHLON

Refs #163 . Obtain the build configure on runtime.
openblas_get_config function returns the configure string.
So far, it supports USE64BITINT, NO_CBLAS, NO_LAPACK, NO_LAPACKE,
DYNAMIC_ARCH, NO_AFFINITY.
Example:
#include <stdio.h>
extern char * openblas_get_config();
void main()
{
printf("%s\n",openblas_get_config());
return;
