Patch openblas to add 64_ suffix when using 64 bit ints

objconv cannot do in-place modification of files

dont overwrite static library with objcopy on freebsd either

fix linking of arpack and suitesparse with 64_ blas suffix

the patched xlahqr2 was using UPPERCASE function names, and the probes
during arpack configure were using the C compiler, sgemm_ and cheev_
need to enable c preprocessor, and disable syntax error on long lines

SPQR also needed -DSUN64

We needed to move the objconv rules to above the openblas rules

Fixes #8842

RFC: Should we backport #8734 to release-0.3 ?
