Well, it turns out that I spoke slightly too soon. The x86 portion was easy, 
like I wrote... but it kept failing on universal macOS builds because the test 
for "is this x86" kept being true. I had to redo it in a way that the code in 
the library compiled even if not on x86-64 (it simply expands to empty now, 
like qstring.cpp), and made the unit test not be enabled in CMake at all if 
you're doing multi-arch macOS.
