CCE15 no longer produces a .ident line, so  look for HPE name in a note section as well

This PR patches the f_check scripts to detect the ifort compiler. With
out this, the value of F_COMPILER is G77 which causes the link phase to
use icc rather than ifort, resulting in missing libifcore.

* Add support for the Cray Fortran compiler

Due to recent perl script conversion, there are some build
errors when compiling openblas with advance toolchain compilers.

* 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)

at least the AMD (aocc) flavor of flang wants to link to a (real or dummy) libomp by default

fixes #2336 (non-recognition of gcc 10) with patch provided by JeffreyALaw.

Both forms are seen on NetBSD (#2288)

Auto-add "-fno-second-underscore" option to make LAPACKE compile (as it calls LAPACK functions that may have gotten a second underscore added otherwise). Also support -R for rpath when parsing compiler directives in f_check

Found via `codespell -q 3 -w -L ith,als,dum,nd,amin,nto,wis,ba -S ./relapack,./kernel,./lapack-netlib`

1. the already deprecated -openmp option was removed in 2018, switch to -fopenmp
2. add leading blank in search for "zho_ge__" symbol to work around misleading tags in the 2018 assembly
Expected to fix #1548

- 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

Without proper recognition of gfortran versions such as
> GNU Fortran (GCC) 4.9.x 20150123 (prerelease)
OpenBLAS assumes the presence of the G77 compiler. Consequently,
`-lgfortran` is missing from the pkg-config file.

The aforementioned compiler is the gfortran compiler in the Android repo
in a commit tagged as `ndk-r14`, cf. Paul Mustière's gfortran build
instructions for Android at https://github.com/buffer51/android-gfortran

the illumos linker can't understand the "-Y/lib"... form that f_check
generates, and -Wl cannot pass options that include commas

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

On FreeBSD, passing extra options to `which` causes it to report a non-zero status:

```
$ which gfortran48 -m64
/usr/local/bin/gfortran48
$ echo $?
1
```

```
$ which gfortran48
/usr/local/bin/gfortran48
$ echo $?
0
```
