* Add automatic fixups for OSX/IOS cross-compilation

* Add OSX/IOS cross-compilation test to Travis CI

* Handle platforms that lack hwcap.h by falling back to ARMV8

* Fix PROLOGUE for OSX/IOS

by catching and working around failures to load modules, and avoiding object-oriented syntax in tempfile creation.
Fixes #1989

Assume cross-compilation if host and target os differ

fixes 1674

clang 3.4 managed to accept the original test code, only to fail on the actual Skylake asm later

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.

This is necessary to avoid the false detection of a cross-compiling
environment.

If the path involves `-`, this would have otherwise detected this as a cross compile suffix.

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/.

This is necessary to avoid the false detection of a cross-compiling environment.

`uname -m` returns "amd64" on some systems.

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