Added HFLOAT16 support for RISCV64
Added shgemm_kernel_8x8 for RISCV64_ZVL128B and shgemm_kernel_16x8 for RISCV64_ZVL256B based on HFLOAT16
The instruction sets used are ZVFH and ZFH, which need to be supported by RVV1.0

This reverts commit bdaa6705ca.

It turns out that PRs 4515 and 4520 break the tests under
lapack-netlib/TESTING which require SECOND and DSECND. IBM
has decided this is a bigger biger problem than the conflict
between lapack second_ and the xlf run time.

do not add LIBNAMESUFFIX to dylib

* Add mixed clang/ifort build on OSX to the Azure CI config based on https://github.com/oneapi-src/oneapi-ci
(and remove debugging tools from the clang+gfortran job)

* Remove extraneous libgfortran dependency of ifort builds

* remove FEXTRALIB from link line of shared library as ifort keeps track of dependencies (and they are different for a .dylib than what f_check got for an executable)

Following two commands have two completely different meanings
perl ./gensymbol objcopy x86_64 _ 0 0  0 0 0 0 "" "64_" 1 0 1 1 1 1 > objcopy.def
perl ./gensymbol objcopy x86_64 _ 0 0  0 0 0 0 "" "64_" 1 0 1 1 1 1> objcopy.def

* make building the bfloat16 BLAS functions conditional on BUILD_HALF

* pass the BUILD_HALF option to gensymbol

* Pass BUILD_HALF as a compiler define for dynamic_arch builds

There is no difference in the way libnames are handle between FreeBSD
and linux or sunos. FreeBSD and DragonFly prefers having sonames as well

icc has known problems with mixed-language builds that ifort can handle just fine. Fixes #1956

Conflicts:
	exports/Makefile

Its exclusion was an oversight on my part.

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.

Rewrite NOFORTRAN conditionals

... so that they do not trigger accidentally when NOFORTRAN is empty/unset

Remove default FEXTRALIBS in NOFORTRAN case

* The DLL is named cygopenblas.dll, not libopenblas.dll
* The import lib (still called libopenblas.dll.a) is installed

Android does not support versioned SONAME entries, ref. #1173

If you want to build LAPACK deprecated functions since LAPACK 3.6.0

make BUILD_LAPACK_DEPRECATED=1

illumos fixes

use different names for `openblas*.renamed` between osx and other unices, fixes
```
Makefile:121: warning: overriding commands for target `../libopenblas64_p-r0.2.15.a.renamed'
Makefile:100: warning: ignoring old commands for target `../libopenblas64_p-r0.2.15.a.renamed'
```

also clean `*.renamed`

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

for adding a prefix or suffix to all exported symbol names in the shared library
Useful to avoid conflicts with other BLAS libraries, especially when using
64 bit integer interfaces in OpenBLAS

Note that since OSX does not have the objcopy utility, setting these options
to non-empty values on Mac requires the objconv tool, available (GPL license)
