This is pretty much how every package does it; nothing special to CDBS.  
I know of nothing in the policy or the reference that ways you should 
pick up CFLAGS from the environment.  In fact, I believe it would be 
totally wrong to do so.  If you want special compilation options, you 
should record them in a makefile.
