Interesting. I was actually thinking more along the lines of checking 
for the presence of environment variables like %VS120COMNTOOLS% (for VS 
12.0 = 2013) or %VS100COMNTOOLS% (for VS 10.0 = 2010).
Your idea would also get the architecture, but make should know that 
already.
Is your fix necessary for SHARED_LIBRARIES=NO or STATIC_BUILD=YES? Or 
both, or any?
