upload your patches to https://android-review.googlesource.com/ :-)

no idea, sorry.

traditionally there hasn't been one, but you can try
qemu_arm-userdebug. it's _supposed_ to not include a VM or anything
though i'm led to believe that right now it's building more than it's
supposed to because some unwanted dependency crept in. still probably
your best choice though.

even just killing AndroidConfig.h (which gets -include'd in every file
that's built) has taken a surprisingly large chunk of my time. (and,
pretty much by definition, the stuff that's left is the hardest stuff
to kill.) the tree is so large, and with so many different users, that
it's pretty hard to make any change to the build. and there's usually
something more urgent to do.
