Just for fun, I entirely (re)built and maintain a bleeding edge up to
date gentoo arm distro (on x86_64 in arm qemu chroot) which now runs
fine on the tablet its own chroot. Build is a bit slow (qemu), but,
with enough x86_64 cores it is acceptable when doing in parallel.

As opposed to cross arm build on x86_64, this method allows to build
everything (and run nearly everything), for example, one can run xterm
(or any xwindows application) to display on a remote xserver. Or one
can also run any deamon/server.
The cross arm build method, on the contrary, chokes on many configure
scripts. It is much faster, but, for example, I could not cross build
perl and much other software.
