* Added ARMV9SME target
* Added SGEMM_DIRECT kernel based on SME1

* Add ARMV5

based on cpuid_arm.c and param.h

During the cross-compilation on x64 host with MSVC for ARMv8, the
build fails as there is no define directives for Generic core.

OpenBLAS: aarch64: Add neoverse-v1/n2 architecture specifics

Missing HAVE_SSE* cmake variables cause cc.cmake to forget about `-msse*` flags

Adjust A53 SGEMM parameters to reflect recent switch to 8x8 kernel

This is the initial patch to support build infrastructure
for POWER10 architecture.

This patch adds support for bfloat16 data type matrix multiplication kernel.
For architectures that don't support bfloat16, it is defined as unsigned short
(2 bytes).  Default unroll sizes can be changed as per architecture as done for
SGEMM and for now 8 and 4 are used for M and N.  Size of ncopy/tcopy can be
changed as per architecture requirement and for now, size 2 is used.

Added shgemm in kernel/power/KERNEL.POWER9 and tested in powerpc64le and
powerpc64.  For reference, added a small test compare_sgemm_shgemm.c to compare
sgemm and shgemm output.

This patch does not cover OpenBLAS test, benchmark and lapack tests for shgemm.
Complex type implementation can be discussed and added once this is approved.

The implementation is a hybird of the ARMV8 one with some of the
improved TX2 rountines along with specifying -march=v8.2-a

* Update DYNAMIC_ARCH list of ARM64 targets for gmake
* Update arm64 cpu list for runtime detection
* Update DYNAMIC_ARCH list of ARM64 targets for cmake and add POWERPC targets

* Fix compiler identification and option setting

* Handle BINARY=32 option on X86_64

* Add xGEMM3M unroll parameters for crossbuild-target CORE2

* Replace bogus mingw64/32bit CI job with actual 32bit build

mingw64 is not multilib-capable, so using an x86_64-mingw with BINARY=32 in the CI was not going to work anyway (but build passed while BINARY=32 was ignored).

1. Supply appropriate values for C/Z GEMM unroll when cross-compiling for CORE2 or ARMV7
2. Add the required xLOCAL_BUFFER_SIZE parameters for cross-compiling CORE2
3. Add -DFORCE_<target> option to getarch when building with -DTARGET=target
for #2245

for #2235

(also copy BUNDERSCORE settings for FORTRAN from the corresponding Makefile)

Fixed core naming for DYNAMIC_ARCH. Corrected GEMM_DEFAULT entries and added SYMV_P. Replaced outdated VULCAN define for ThunderX2T99 with ARMV8 to get basic definitions back. For issue #1908

and create config target directory for cross-compiles.

* prebuild.cmake: Put quotes around path names that may contain whitespace
(Copied from alexkaratakis' PR #1295)
* kernel/CMakeLists.txt: Fix common_lapack header inclusion and DYNAMIC_ARCH generation of ?neg_tcopy and ?laswp_ncopy files
* lapack/CMakeLists.txt: Use correct template for ?laswp_(plus,minus) functions

Fix typos and bad if statements discovered in 0.2.20.

Add support for not having host compiler as CMake cannot detect such a compiler.
Add support for not using getarch.
Successfully builds Android ARMV8. Any target can be added by supplying the TARGET_CORE config in prebuild.cmake.
