That would be awesome. I don't think a libre OS would put an SDK in it's 
repositories though if it was still attached to the replicant/android 
OS. Not that it needs to be in any repositories, but it would be nice.

A while back on this list, I mentioned how now the stock android 
toolchain can be built without downloading the main OS [1]. I think it 
wouldn't take much to patch a new version judging by the current 
replicant SDK patches, if that's anything to go by [2]. Of course, it 
would need to be compatible with the new version of replicant, which 
apparently will be based based on android 6.0
