partial fix for #1574 - the problem with lapack_testing.py looks like an upstream bug

With this change, OpenBLAS builds and all tests pass on OpenBSD 6.2
using Clang. Tested on x86-64 only, with and without DYNAMIC_ARCH=1.

- retry fortran compiler test with aix-specific option if generic -m32/-m64 fails
- pass any custom ARFLAGS to lapack
- no addition of -m32/-m64 to the CFLAGS and FFLAGS on AIX

The installation instructions as shown after successfully compiling
OpenBLAS are wrong because this arguments used during compilation have
to be provided to Make again.

* Disable ReLAPACK by default; mention it in final build message if included

* Add files via upload

* Add files via upload

* Add files via upload

If you want to build LAPACK deprecated functions since LAPACK 3.6.0

make BUILD_LAPACK_DEPRECATED=1

illumos fixes

2) If OpenBLAS cannot find Fortran compiler, it will only build BLAS
(without LAPACK).

Fixed c/zgemm, zgemv computational error of haswell, piledriver, bullldozer, and
barcelona on Windows.

fix default prefix handling in makefiles

PREFIX wasn't communicated to Makefile.install (where it matters)
by Makefile. The result is that the default PREFIX is empty and
OpenBLAS was being installed in /lib.

a fortran compiler, please try make ONLY_CBLAS=1.

This mode only compiler CBLAS without BLAS fortran interface and LAPACK.
