* Force portable code
* Switch to old MMX instructions, avoiding SSE & SSE2 instructions.
* Less agressive, leave verus code (which checks for it) using advanced instructions.
* Compiling only for windows
* Update .gitlab-ci.yml
* Try -march=native for C++ code generation.
* Tweaking machine architecture settings.
* Try native alone.
* Also get LIBCRYPTOCONDITIONS to -march=native
* Switch other lib to native as well.
* Try switching back further for CPU architecture.
* Even lower end settings.
* Turn on symbols.
* Use sse2,3 and 4 capable x64.
* Once again let verus lib use advances instructioins since it checjs via CPUID at run time.
* Modify a few more makefile entries.
* Switch to AMD model similar to our test system.
* Get snark makefile to k8 too.
* Yet another -march to modify to k8, or two of them.
* Brute force k8 settings, comment non-portable code out.
* Put the condition on cpuid back.
* Put non-portable advenced instruction code back
* Enable instructions.
* Add lib for separate settings.
* Update .gitlab-ci.yml
* Update .gitlab-ci.yml
* Update .gitlab-ci.yml
* Update .gitlab-ci.yml
* replacing k8-sse3 specific flags to x86-84
* updating versions
PATH variable containing spaces cause build failure
Spaces in PATH variable is creating build issues (observed on macOS). For example "VMware Fusion" adds itself to PATH like `/Applications/VMware Fusion.app/Contents/Public`.
