TL;DR I'm finding it a little bit confusing but can't propose any better 
alternatives so I have no objections :)

Some thoughts:
* arm64 + armv7 is a universal binary, arm64 + armv7 + i386 - well, 
still universal binary too :)
* OSX_ARCHITECTURES affect architectures on iOS. Probably it should be 
IOS_ARCHITECTURES or just ARCHITECTURES (though MACOSX_BUNDLE works same 
way)
* OSX_ARCHITECTURES=armv7 -> build armv7, OSX_ARCHITECTURES=armv7,arm64 
-> build universal armv7+arm64, but OSX_ARCHITECTURES=armv7,arm64,i386 
doesn't build armv7+arm64+i386 binary
* hard to say anything about future improvements, like if it will be 
easier to implement universal binary in build directory on Android, then 
*_ARCHITECTURES looks better. but if it will be easier to build one 
architecture then add extra code to add more on install then 
INSTALL_UNIVERSAL_BINARY for all platforms looks better
