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.

MSVC treats the declaration of omp_in_parallel and omp_get_num_procs without the modifiers __declspec(dllimport) and __cdecl as a redefinition.

Seperated mips and mips64 files.
Configurations support for mips 32 bit.

to be used on armv5 and new platforms

- use on arm, arm64 and any new platform
- use faster integer math instead of double
- use similar scale as rdtsc so that timeouts work

Disable CBLAS and LAPACK.

e.g.
make HOSTCC=gcc CC=arm-linux-androideabi-gcc NO_LAPACK=1 TARGET=ARMV7

In Android NDK, it uses armeabi-v7a-hard ABI.
TARGET_CFLAGS += -mhard-float -D_NDK_MATH_NO_SOFTFP=1
TARGET_LDFLAGS += -Wl,--no-warn-mismatch -lm_hard
For more information, please check hard-float example at
android_ndk/tests/device/hard-float/jni/.

For gemv_t, directly use malloc to create the buffer.

Don't have unistd.h in MSVC.

Chagned YIELDING to use the YeildProcessor macro.

I used a smaller threshold since the stack size is 1MB on windows.
