The Google Code page is actually not empty [1]. The rest will be more
populated once more testing has been done.

I've chosen to provide the overlay / source / binaries as a tarball
for now until a few more people have tested it out. Actually, this is
a good reminder to put together a small qemu image so that people
could easily try out. I've been putting that off since work has been
fairly busy lately. Also, I really need to upload the arm toolchain I
built too.

Note to self...

Yes, please see the link at [1].

It would be something like that except for two exceptions.

1) The arm port of bionic is only arm eabi compatible (which implies
little-endianness IIRC)
2) The 'android' vendor string has no effect as far as crossdev is
concerned. It's better to use softfloat, hardfloat, or unknown. Please
see the crossdev and embedded guides at [2], [3]

I would suggest something more like

crossdev -S --g 4.6.0 --target armv7a-softfloat-linux-bioniceabi

(but only after you've set up the overlay).

For further discussion, please write on the gentoo-embedded mailing
list [4]. You can also check out this thread [5] for more information.

Cheers,

Chris
