That isn't true, if you build a target and a native version your build
time does increase. Using BBCLASSEXTEND does improve parsing time over
having two separate recipes though.

I did talk with Darren about why the recipe is the way it is and there
are some pretty nasty issues with the way grub builds itself. I'm
therefore ok with this as a version 1 and we can see whether there are
any issues that result which need us to rethink the way the recipe is
constructed. 

Its currently behaving very like the way the binutils/gcc cross recipes
will end up (see the separate thread with Matthew) Perhaps it should be
called grub-efi-cross even if it uses native.bbclass.

Cheers,
