The long time is because your build system is half broken, as I said: you  
need proper dependencies on targets, and a proper separation of targets. At  
the moment you're rebuilding the whole offline-root with each `make doc'.  
That's taking almost the whole of the nearly 3min. This stems from two  
problems: 1) the website should be a separate target and 2) you're not  
checking for any dependencies on the offline-root target, instead you have  
these python scripts which execute everything everytime and take very long  
to finish.

Your use of recursive make is another issue. `make doc' is actually a loop  
through every single subdir, whereas we know there are only a few subdirs  
that need visiting, for example. But actually that's still pretty fast when  
there is nothing to be built, and is only a fraction of the 3min you're  
experiencing.
