  1. ENH: distutils: add support for ILP64 OpenBLAS (generic symbol suffix) 

    Generalize the ILP64 BLAS/LAPACK symbol name handling to deal with
arbitrary prefix/suffix.

The build-time behavior is changed so that HAVE_BLAS_ILP64 and
BLAS_SYMBOL_SUFFIX/PREFIX defines are added to compile options
as appropriate.

Mainly to make autodetection of BLAS/LAPACK easier for downstream
numpy.distutils users, add get_info aliases 'blas_ilp64_opt',
'blas_ilp64_plain_opt', and 'blas64__opt' for any/no/""&"64_"
prefix&suffix, and the same for lapack. (Due to the way system_info
works, each also gets a separate class.)

In addition to openblas64_ which has a fixed suffix, add the (by default
suffixless) openblas_ilp64, which correspond to the most likely cases to
be present.

    Changing these to support ILP64 blas was missed in numpygh-15012
