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)
from http://www.agner.org/optimize/#objconv

Adding $(EXTRALIB) adds this flag when things are built with
msys2 on windows. Without this the build fails.

Avoids problems of libgfortran not being found.

The aim is to restrict the symbols exported from openBLAS, but for dynamic libraries --retain-symbols-file has the opposite effect intended. It removes symbols from the .symtab section of the library, which is used by tools such as debuggers, profilers, objdump etc. but does not remove them from .dynsym, which is the section used by the runtime when loading the binary.

In short, using --retain-symbols-file like this doesn't prevent symbol leakage but does prevent tools from analyzing applications linked with openBLAS.

This patch improves tool support for openBLAS applications but does not address symbol leakage through .dynsym.

a fortran compiler, please try make ONLY_CBLAS=1.

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

For LAPACKE, use LAPACK_COMPLEX_STRUCTURE.
The reson is lsbcc didn't define complex I in complex.h.
