Make the build chain work on OSX about spyre

[hillu]

You should not need to install openssl via homebrew because as a build-dependency of YARA, it is supposed to be built using the rules in 3rdparty.mk.

Sadly, I don't have access to a MacOSX build environment (and I don't want to do the edit-compile-rinse-repeat dance through a CI service). I am currently working on getting Spyre to build on FreeBSD. This is all about the 3rdparty libraries and most of this stuff can probably be transferred to MacOSX.

Hi after first testing there are some issues with static builds on MacOS:

This maybe related to this post, of course we want to have a static build of spyre:

https://stackoverflow.com/questions/3801011/ld-library-not-found-for-lcrt0-o-on-osx-10-6-with-gcc-clang-static-flag.

I'm currently investigating if this works: https://dropline.net/2015/10/static-linking-on-mac-os-x/

Fixed via 797d6ed; Thanks to @n3x77 for testing.
