cdc668d82b Add a "sgemm direct" mode for small matrixes 
OpenBLAS has a fancy algorithm for copying the input data while laying
it out in a more CPU friendly memory layout.

This is great for large matrixes; the cost of the copy is easily
ammortized by the gains from the better memory layout.

But for small matrixes (on CPUs that can do efficient unaligned loads) this
copy can be a net loss.

This patch adds (for SKYLAKEX initially) a "sgemm direct" mode, that bypasses
the whole copy machinary for ALPHA=1/BETA=0/... standard arguments,
for small matrixes only.

What is small? For the non-threaded case this has been measured to be
in the M*N*K = 28 * 512 * 512 range, while in the threaded case it's
less, around M*N*K = 1 * 512 * 512

7639f2e1f0 Rewrite the conditional for OSX to fix cmake parsing on others 
The Makefile variable parser in utils.cmake currently does not handle conditionals. Having the definitions for non-OSX last will at least make cmake builds work again on non-OSX platforms.

2fc712469d Avoid creating spurious non-suffixed c/zgemm_kernels 
Plain cgemm_kernel and zgemm_kernel are not used anywhere, only cgemm_kernel_b etc.
Needlessly building them (without any define like NN, CN, etc.) just happened to work on most platforms, but not on arm64. See #1870

Fix two mistakes on Arm64 builds

31a490ea88 Fix two mistakes on Arm64 builds 
* Falkor is an ARMv8.0 with ARMv8.1 features, and chosing armv8.1-a for
   march generates instructions it cannot cope with. Reverting it back
   to armv8-a.
 * ThunderX2's build was left with a #define VULCAN, which made it miss
   the right compiler flags in Makefile.arm64, although it did create
   the right library in the end.
